You Really Do Want to Read the Directions
Hey, we get it. You just got your new enclosure kit and want to start using it as fast as possible.
How hard can assembling a few plastic panels possibly be? It’s not really that hard, assuming
you’re following the directions, but try to use brute force and you’ll end up working your way
through your vocabulary of swear words. While the acrylic pieces in the kit are strong, they are
still plastic and will break if bent far enough. The ghosts of the broken panels that have gone
before you have become much stronger than you could ever imagine, and are whispering into
your ear, “just be a little careful”. !
Before you Start
Is This Manual for Yo u r Kit?
This installation manual covers the enclosure design for the Creality Ender 3 S1 ONLY.
The Ender 3 V1, V2, and Max all require different enclosures! If you have a different version of
the enclosure please read previous versions of the manual available on the website.!
Is your Printer Customized?
#
If your printer is stock then no customization is needed. If you have customized the printer,
you should examine any modifications to make sure they don't block the panels. If part of one
of the panels is blocked, you can use a laser or drill to customize one or more panels. This
should be done before removing the plastic or paper covers on the acrylic panels.
Cutting acrylic requires great care as the plastic is prone to crack if mishandled.
Preparing the Printer!
Remove any filament from the hot end (will require heating the hot end) and remove the
filament spool from the spool holder.!
Turn the printer offand unplug the power cable from the printer’s power supply. !

Don’t Panic If You See This!!
"
If you can’t see through the plastic, please
don’t panic! What you’re seeing is just the
plastic or paper protective covering.!
When plastic sheets are manufactured they
are covered by either a paper (brown
colored) or plastic (white) covering to protect
against scratches. Follow the directions
below to remove the cover and discover the
beautiful plastic underneath. !
To remove the covering from an acrylic
panel, lay the panel flat on a table. Then peel
up a corner of the covering and CAREFULLY
and SLOWLY pull horizontally to the sheet to
reduce the lateral forces that would bend the
acrylic. This video shows just what to do. $

Everything You Wanted to Know About Screwing But
Were Afraid to Ask
Probably the most confusing thing about assembling this enclosure will be which fastener or
screw to use. Luckily it's pretty easy to figure out once you know the system. While the exact
screw to use will be detailed in each section of the manual, you probably won't need to refer to
it once you know the secrets.!
The most common screw is the 12mm hex cap head screws. The 12mm screws are long
enough to attach things to the acrylic front, top, sides and back. Each section will describe
exactly which screw to use, to read carefully and use the specified screw for the best results. !
The actual length of the "long" screws to attach the fan and or filter will vary depending on the
depth of the particular shipment of fans we happen to get that month. They won't be hard to
spot since they'll be the longest thing in the bags.!
Finally, and we can’t stress this enough:!
D O N ’T O V E R T I G H T E N T H E S C R E W S
Leave the screws a little loose until the end adjustment phase. During that process you’ll be
hand-tightening until the screws are snug, but you can easily use so much force the plastic
pieces or the acrylic crack. Please don’t be that guy. $

Assemble Panels
1. The Front Panel!
Each of the corners on the enclosure will be held together by the connectors pictured
below. There are only two versions L and R, which can be identified by the letters
stamped on the inside. The opposite connectors are identical, i.e. Bottom Right is the
same as Top Left. In all cases the surface of the connector with the cutout pattern
faces front or back.!
The front door is designed so that the latches are on the left. Attach the corner
connectors on the back side of the door frame using the provided cap head 12mm
screws. See the photos below. The top of the connector should be flush with the top
of the acrylic.!
"
There are also smaller connectors at the top and right side when viewed from the front.

The front should look like the picture to the right.$

!
Locate the magnetic latches and use the wood screws to
attach them to the latch mount. Hand tighten and make sure
they’re secure, but do not over tighten or they may strip. The
latch can be later adjusted front-to-back to make sure the door
is flush with the door frame. !
Each latch mount is attached via three screws. Use the
30mm cap head to secure the latch mount to the door
frame. You’ll use 2 M4 12mm screws to attach the latch
mount to the right-side panel later in the assembly. !
Attach the hinges to the door and door frame using M4
12mm screws and nuts. There will be some play in the
hole size so that you can adjust the door to swing freely.!
Attach the doorknob by first inserting
the square M4 nut into the slot. Use a
16mm cap head screw to attach the
door.!
Now that the latches are mounted it is time to connect the strike
plates. Each plate comes with a squishy adhesive covering the
same size as the plate. Carefully attach the adhesive side to the
acrylic at the location of each latch. Then, adjust the width of the metal strike plate so
that it is held on by the pressure of the two sides of the plate. The adhesive covering
will keep the metal strike plate from scratching the acrylic. !

2. Left Side Panel
Attach the left side to the front forming an L-shape that will stand up on its own, then
attach one L and one R connector at the back. The Ender 3 S1 design technically
doesn’t need a door, but it allows for additional access to the extruder. The latch
mounts are smaller than the front, although the magnetic latch attaches in the same
way with wood screws. The parts for the side door will be in a separate packet.!
Attach the door hinges, latch mounts, strike plates, and
the knob, and the assembly will look like the illustration to
the right. Don’t forget the mid-panel connectors at the
back left and top.!
As with the front door, adjust how the door hangs by
loosening the hinge screws, using the strike plates to hold
the door to the latches, and then tightening the hinge
screws.!
Note that the left side will also be the location of the fresh air intake vent, but that will
be installed after the enclosure is placed over the printer.!

3. Back Panel
The back of the enclosure is shown below. The four corner connectors are mirror
images of the front. The large hole is either for an air filter (purchased separately) or
can be covered up by the included plastic disc using M4 12mm screws. On the top
and on each side are “mid panel corner connectors”, which are basically simple L-
shapes. !
!
Make sure the fan is blowing air out of the
enclosure and NOT into it. Confirm the direction of
the fan by plugging it into a USB power supply
before attaching the filter. The round label should
be on the outside!
The fan should be attached on the outside of
the enclosure.
The fan should be oriented to pull air OUT of the
enclosure. !

Use the long screws included in the fan packet to attach the fan. The length of the
screws may change depending on the depth of this
particular shipment of fans.!
The back panel also contains the removable grommet
cable portal. Locate the grommet and insert it into the
grommet holder. This is where you’ll insert the power
cable, USB cable, and any other wires you want to run
in or out of the enclosure.!
Insert the grommet holder/grommet combination into
the U-shaped hole in the right-side panel. This will enable
you to slide the enclosure offand onto the printer without
unplugging the cables.!
4. Right Panel
!

Attach the right panel as shown above at each of the four corners. You can now
attach the latch mount on the front using 2 M4 12mm cap head screws.!
The new Ender 3 S1 has a different display that
inserts into a mounting platform that also
attaches via the two corner connector screws on
the right panel. Rather than use the 12mm M4
screws as before, you’ll use the longer 16mm M4
screws to attach both the corner connector and
the display mount.!
!
The kit comes with a cable to attach the display on
the outside of the enclosure. The cable goes through
the enclosure in the slit as shown to the right.!
5. Top Panel
Before attaching the top, now is
a good time to insert the support
beam. It is a tad wider than the
enclosure so that it doesn’t fall
out when moving the enclosure.!
Copyright 2022 3DUpfitters

Use access through the doors to attach
the top of the enclosure using M4 12mm
screws. You’ll attach the top on the four
corners, and to each of the mid-panel
connectors as well. The slit is towards
the front, and the small access hole for
the filament runout sensor cable should
be on the right. The view shown at the
right is from above facing the front of the
printer.!
!
Attach the filament sensor to the L-
bracket as shown using the silver screw
that was supplied with the printer to
attach the sensor to the Creality spool
holder. !
Instead, you can use any spool holder
on top of the enclosure and run the
filament through the filament sensor and
directly to the extruder. Note: 3D
UPfitters spool holder not included.!

6. Install Vents
You should now place the enclosure over the 3D printer. !
The front fresh air vent is inserted
from the outside and attached using
M4 12mm screws. This will bring in
cold air to the air intake vent of the
case, cooling the electronics inside.
It’s important to keep the fan on the
back panel running in order to help
draw air through the case’s vents
and to the outside, especially when
printing PLA and PETG. !
If you forget to turn on the fan
when printing PLA your printer will
probably clog. !
If that happens use a 3D printer needle (available in many places online) to remove the
clog. This technique is easy and works most of the time. !
It is acceptable to turn offthe fan when printing ABS or ASA in order to bring the
temperature into the ideal range, but be sure to turn the fan back on when you’re
finished, especially if you are venting or filtering the air to remove VOCs.!
Note that the lid fits right into the vent slots,
helping to form a seal. Slide the 3D printer
towards the front up against vent. !
The right tray is labeled as such and is
inserted from the outside as well. As you
insert the tray be sure to lift up the right side
of the printer so that the tray slides under
the square rubber foot. This foot fits into
the square hole in the vent.!

7. Tighten Gaps
Once the enclosure is completely put together, it is time to make sure that each of the
panels is held tightly to each adjoining panel. The connectors are designed with a
small amount of play that allows you to make small adjustments for the perfect fit. !
1. Loosen screws on the panel to move.!
2. Push that panel into place. You may need a friend to hold it tightly in the right spot.!
3. Re-tighten the screws to hold the panel. Only tighten enough to hold the pieces
snuggly. DO NOT OVER-TIGHTEN! These parts are sturdy, but they’re still all made
out of plastic.!
Repeat the product, going around the enclosure looking to make sure all of the panels
are flush to each other.!
8. Assemble Spool Holder
Instructions to assemble the spool holder are
available online in the product description, but it’s
not too hard to just wing it. !
The location that will give the least resistance is
placing the spool holder directly to the left of the
printer. Many people who are low on space,
however, place the spool holder on top, which
shouldn’t make too much of a different in print
quality.!
Of course, if you don’t like this spool holder you
are free to use whatever type of freestanding
spool holder you wish; there are hundreds of
designs available on Thingiverse. !
The filament feeds into the extruder through
the gaps in the side doors.

9. Temperature Gauge
The optional thermometer will let you know approximately what temperature it is inside
the enclosure. It attaches to the left side of the door piece using the same hole as the
top-most corner connector as shown. It comes with a longer screw to fit through
everything.!
!
10. Managing Enclosure Temperatures
There's not much to a 3D printer enclosure. Although ours look fancy, functionally
they're not much different than putting a card box over the printers since both designs
are passively heated by the heated beds.!
We generally get two types of customers:!
1. Those interested mostly in air quality.!
2. Those interested mostly in print quality.!
The problem is those two goals use two different techniques in terms of airflow. For
the best air quality, as much air as possible needs to come into the enclosure and then
be vented or filtered out. All of our enclosures come with fans, and we've chosen the
CFM ratings to match the cubic size of the enclosures. This ensures that for filament
types like PLA, which don't like the heat there's enough airflow to keep the
temperatures in the safe zone. !

At the same time, you want the internal temperatures higher for filaments like ABS,
which happens naturally because the recommended bed temperatures are much
higher than for PLA, typically in the 105-120C range. With the fans turned on we shoot
for internal temps between 35C and 40C for 3D printers that use E3D hot ends,
because E3D recommends that temp range to avoid clogging. By keeping the
temperatures in that range it puts the least stress on the equipment and follows the
manufacturer's guidelines.!
This works great for people either interested mostly in air quality or those who are risk-
averse and don't want to take a chance of clogging their hot ends or decreasing the
useful life of their printers.!
More experienced 3D printer owners though, those for whom a clogged nozzle is an
acceptable risk, might want to run the temperatures higher for less warping of ABS
parts or to print nylon. In those cases, you can turn offthe fans or even print one of
the vent covers and just not vent at all. For our internal print farm, we do the later on a
couple of machines where the temperature when printing ABS gets as high as 46C.
They've been running like that for years with no clogging and even with no venting of
the power supplies, we've never had a power supply fail either. Obviously, your mileage
may vary, as it depends on a lot of variables such as filament quality and the quality of
the power supply in your printer.!
If you're looking for the highest temperature's possible, try turning the bed heater
on for an hour before you print. !
The other part of the equation is the printer design. Those printers where the hot end is
at the top of the enclosure make it easier to achieve higher temperatures because the
hot air rises to the top, and the vertical hot end position is fixed. Those printers with
the hot ends at the bottom are always going to have more problems managing
temperature simply because the temperature is more likely to vary as the hot end goes
from the bottom to the top of the enclosure.!
If you're looking to achieve a particular temperature with your enclosure, let us know
and we'll give some advice on how to manage, but its really not that hard: !
Lower Temperature = More Air Flow!
Higher Temperature = Less Air Flow
