INTRODUCTION
Before you begin on your journey, a word of caution.
In the comfort of your own home you are about to assemble a robot. This
machine can maim, burn, and electrocute you if you are not careful. Please
do not become the rst VORON fatality. There is no special Reddit air for that.
Please, read the entire manual before you start assembly. As you begin wrenching,
please check our Discord channels for any tips and questions that may halt your progress.
Most of all, good luck!

PART PRINTING GUIDELINES
The Voron Team has provided the following print guidelines for you to follow in order to have the best chance at
success with your parts. There are often questions about substituting materials or changing printing standards, but
we recommend you follow these:
3D PRINTING PROCESS
Fused Deposition Modeling (FDM)
MATERIAL
ABS
LAYER HEIGHT
Recommended: 0.2mm
EXTRUSION WIDTH
Recommended: Forced 0.4mm
INFILL TYPE
Grid, Gyroid, Honeycomb, Triangle or Cubic
INFILL PERCENTAGE
Recommended: 40%
WALL COUNT
Recommended: 4
SOLID TOP/BOTTOM LAYERS
Recommended: 5
PRINT IT FORWARD (PIF)
Often times community members that have issues printing ABS will bootstrap themselves into a VORON using
our Print It Forward program. This is a service where approved members with VORON printers can make you a
functional set of parts to get your own machine up and running.
Check Discord if you have any interest in having someone help you out.

HOW TO GET HELP
If you need assistance with your build, we’re here to help. Head on over to our Discord group and post
your questions. This is our primary medium to help VORON Users and we have a great community that
can help you out if you get stuck.

PRIMARY COLOR
Example z_joint_lower_x4.stl
These les will have nothing at the
start of the lename.
ACCENT COLOR
Example [a]_tensioner_left.stl
We have added “[a]” to the front of any
STL le that is intended to be printed
with accent color.
QUANTITY REQUIRED
Example [a]_z_belt_clip_lower_x4.stl
If any le ends with “_x#”, that is telling
you the quantity of that part required to
build the machine.
FILE NAMING
By this time you should have already downloaded our STL les from the Voron GitHub. You might have noticed that we have
used a unique naming convention for the les. This is how to use them.

THIS IS JUST A REFERENCE
This manual is designed to be a simple reference manual. Building a Voron can be a complex endeavour
and for that reason we recommend downloading the CAD les off our Github repository if there are
sections you need clarication on. It can sometimes be easier to follow along when you have the
whole assembly in front of you.

BUTTON HEAD CAP SCREW (BHCS)
Metric fastener with a domed shape
head and hex drive. Most commonly
found in locations where M5 fasteners
are used.
ISO 7380 -1
SOCKET HEAD CAP SCREW (SHCS)
Metric fastener with a cylindrical head
and hex drive. The most common
fastener used on the Voron.
ISO 4762
HEX NUT
Hex nuts couple with bolts to create a
tight, secure joint. You’ll see these used in
both M3 and M5 variants throughout this
guide.
ISO 4032
HARDWARE REFERENCE
POST INSTALL T-SLOT NUT (T-NUT)
Nut that can be inserted into the slot of
an aluminium prole. Used in
both M3 and M5 variants throughout this
guide. Often also called “roll-in t-nut”.
HAMMERHEAD NUT
Nut that can be inserted into the slot of
an aluminium prole. Used
exclusively for panel mounting, all other
components use T-Slot nuts.
SELF TAPPING SCREW
Fastener with a pronounced thread
prole that is screwed directly into
plastic.
FLAT HEAD COUNTERSUNK SCREW (FHCS)
Metric fastener with a cone shaped head and
a at top.
ISO 10642
HEAT SET INSERT
Heat inserts with a soldering tip so that
they melt the plastic when installed.
As the plastic cools, it solidies around
the knurls and ridges on the insert for
excellent resistance to both torque and
pull-out.

SHIM
Not to be confused with stamped
washers. These are used in all M5 call-out
locations in this manual.
DIN 988
IDLER
GT2 idler used in the motion system of
the Voron.
PULLEY
GT2 pulley used on the motion system
of the Voron.
HARDWARE REFERENCE
F695 BEARING
A ball bearing with a ange used in
various gantry locations.
THUMB NUT
Used in the print bed as a spacer.
DIN 466-B
625 BEARING
A ball bearing used on the Voron Z drives.
WASHER
Usually stamped from sheet metal this
type of spacer is not as consistent in
tickness as the shims are. Only used in
M3 size.
DIN 125
SET SCREW
Small headless screw with an internal
drive. Used in pulleys and other gears.
Also called a grub screw.
ISO 4026

BALL-END DRIVER
Some parts of this design require the use of a
ball-end hex driver for assembly. We recommend
you get a 2.0mm, 2.5mm and 3mm one.
INTRODUCTION
2.5MM HEX DRIVER
The 2.5mm hex driver will see a lot of use in this
build. A quality driver is strongly recommended.
Refer to the sourcing guide for suggestions.
ADDITIONAL TOOLS
We provide additional tool recommendations in
our sourcing guide. Visit https://vorondesign.com/

tab at the bottom of the page.

BLIND JOINT BASICS
Blind Joints provide a cost effective and rigid assembly method.
The head of the BHCS is slid into the channel of another
extrusion and securely fastened through a small access hole in
the extrusion.
If you’ve never assembled one before we recommend you
watch the linked guide.

FRAME ASSEMBLY
This design relies on blind joints to
assemble the frame. We outlined the
basics of blind joints on page 10.
More tips on how to assemble a
frame are linked below.
BUILD ON A FLAT SURFACE
Build the frame on a glass or granite surface
to ensure you can get it as square as possible.

POSITION BED EXTRUSIONS
Find the centreline of the printer
and position the bed extrusions as
shown in the diagram to the left. The
distance between the extrusions is
130mm centred on the centreline of
the printer.
1/2 printer width for standard sizes:
250 spec 205mm
300 spec 230mm
350 spec 255mm

ALL UNITS ARE METRIC
If a unit is not specied
assume it’s metric.
All distances are called out in
millimeters.
