Additional tools required for this assembly section:
Phillips screwdriver PH1
if necessary drill with 3,5mm drill bit
Packages overview
Package 0: Delivered carton
Package 1: Screws (SC)
Package 2: Spare Parts (SP)
Package 3: Custom Metal Parts (CM)
Package 4: Extruder Barrel (EB)
Package 5: Electronics (EL)
Package 6: Tools (TO)

Step 1:
3D printing:
2x rails FG07 (on the picture you can see an old representation of 4 short rails)
1x slide part 1 FG08
1x slide part 2 FG09
1x spiral axis for 1,75mm part 1 FG10.1
1x spiral axis for 1,75mm part 2 FG10.2
1x Axis holder right FG11
1x snap part 1 FG12
1x snap part 2 FG13
1x Plow FG14
1x Axle holder left FG15
2x Stopper FG16

Step 2:
Remove from package 1:
9x wood screw 2.5x12 (SC01)
7x cheese head screw M4x10 (SC05)
1x hammer nut (SC16)
1x slot nut M4 (SC17)
Remove from package 2:
8x ball bearing 4x13x5 (SP09)
1x pressure spring 6mm (SP17)

Step 3:
Remove tool from package 0: Aluminum profile 160mm (FR05)
Step 4:
Insert the four FG07 rails into the groove of the aluminum profile. Two pieces opposite each
other. (on the picture you can see an old representation of 4 short rails)

Step 5:
Tool from package 6: Allen wrench 3mm (TO07).
Fasten four ball bearings 4x13x5 with a cheese head screw M4x10 each to the carriage part 1.
If the holes turn out to be too small, you can drill them out with a 3.5mm drill bit. If the holes are
too large, you can additionally secure the screws with a little superglue.
Step 6:
Tool: Phillips screwdriver PH1
Fasten the carriage part 2 to the carriage part 1 using the wood screws 2.5x12. Holes are
provided in slide part 1 for this purpose. Make sure that the alignment is correct.

Step 7:
Now push the carriage onto the aluminum profile. The ball bearings must run in the guide rails.
The carriage should be able to be pushed with slight resistance without hooking. If this is the
case, the guide rail can be reworked again with the key file. When the carriage runs easily, it is
removed again.
Step 8:
Tools: Phillips screwdriver PH1, warding file square.
Place the two parts of the spiral axle on top of each other and insert two ball bearings 4x13x5
into the designated places at the ends of the axle. Pay attention to the alignment. The lateral
holes for the screws must fit on each other. The two parts of the spiral axle are screwed
together with three wood screws 2.5x12. Finish the spiral with the key file so that the edges at
the junctions of the two parts are removed and all surfaces are relatively smooth. Be careful not
to remove too much material in the process. See also pictures on the next page.

Step 9:
Insert a ball bearing 4x13x5 into the axle holder right (FG11) and screw it tight with a wood
screw 2.5x12. To do this, place the ball bearing in the opening provided for it, on the elevation
provided for it.

Step 10:
Turn the entire extruder so that you are looking at it from behind.
Step 11:
Tool: Phillips screwdriver PH1
A ball bearing 4x13x5 is screwed onto the snap part 1 (FG12) with a wood screw 2,5x12.
screwed. The ball bearing must be centered on the elevation provided for this purpose.

Step 12:
Tool: Phillips screwdriver PH1
Screw a wood screw 2.5x12 into the snap part 2 (FG13). Turn the screw in only so far that it
does not yet come out on the opposite side. Align the two parts so that the side holes face each
other. Then you can place the 6mm pressure spring (SP17) between them and insert the ends
of the spring into the holes.
Step 13:
Tool: Phillips screwdriver PH1
The now assembled latch mechanism is inserted into the groove of the aluminum profile. See
picture. If the parts do not slide freely, the print parts must be reworked by filing or grinding.
Tension the spring by pushing the detent part 2 further into the groove. The correct spring
tension is achieved when there is approx. 61mm distance to the outer edge of the groove. Then
tighten the wood screw so that nothing can move. See also pictures on the next page.
