2. Platform assembly
Assembly time: 1h30
Required kit elements:
- Printer-box base
- M4 screws and M4 nuts
- M3 screws and M3 nuts
- 2 cross-beams
Printed parts:
- 4 corner pieces with the 4 box feet
- 2 cable guides
- 4 foot base (depending on the kind of feet you have chosen)
- 3 parts for the air input
- 1 piece for the cooling of the printer’s mainboard
Step 1 Preliminary information
This is the main element of the printer-box. We call it the platform.
These 2 pieces are the cross-beams. They are used to stiffen the platform. The kit contains another cross-beam, which will be used for the roof of the box.
At the front of the platform, there is a place for the printer control panel and a free slot for Raspberry PI or temperature control mod.
At the back of the platform is the power supply for the printer and the power supply for the printer-box, which is needed for the mods.
On the right hand side is the slot for the air input.
At the bottom of the platform there is a hole for ventilation of the printer’s mainboard.
Step 2 Mounting the platform corners
Insert 1 M4 nut into each of the slots.
This may require a little pressure.
Insert 1 corner piece into each corner of the base.
For right insertion of corners, slide them from the top.
Fix the corner pieces to the base with M4 screws.
Step 3 Attaching the printer-box feet
Turn the printer-box over. Insert and tighten the 2 screws to hold the printer-box foot.
Proceed in the same way with the 4 corners of the base.
Step 4 Preparing the side filtration module
Insert an M3 nut into each of the slots of the filtration module.
Tips: Handle the nut with the Prusa clamp.
Cut the filter (Swiffer piece or surgical mask) to the right size.
Tip: You can use the base of the holder as a template.
Place the filter on the base of the holder and close the holder.
Add the sliding part for air entry adjustment.
Your filtration module is ready.
Step 5 Mounting the side filtration module

Position the filtration module on the outside of the base and fix it with 4 screws M3x6mm (nut inside).
Step 6 Mounting of the ventilation grid
Insert nuts 4 M3 square nuts into each of the ventilation grid slots.
Position the ventilation grid and fix it with 4 M3x6mm screws.
The grid is inside the printer-box, so the screw head is under the printer-box.
Step 7 Mounting the cross-beams
For this step, you will need 2 crossbeams and 2 cable rail mounting.
Place the 2 lower cross-beams on the printer-box base.
You will need 6 M4 screws to fix the cross-beam to the printer-box base.
Place 1 cable guide on each of the lower cross-beams against the left side of the base. Screw the cable guides to each cross-beam (nuts on the inside).
Screw the cross-beams to the base (M4 nuts inside the printer-box).
Do not put any screws in the intermediate positions for now.
Step 8 Mounting the foot braces
You can choose between 3 types of foot braces:
Foot braces for Prusa Mk3 shock absorber: see step 8.1.
Foot braces for Printer-box on Printer Mk3: see step 8.2.
Foot braces for squash balls on printer Mk2 / Mk3: see step 8.3.
Step 8.1 Mounting the foot braces for Prusa Mk3 shock absorber
Position the 4 foot braces on the lower cross-beams as shown in the picture.
The parts are identical but are placed differently: do not choose the wrong holes.
Screw the foot braces to the cross-beams (screws on the outside).
Step 8.2 Mounting the Printer-box foot braces on the Mk3 printer
The parts are identical but are placed differently.
Position the first 2 foot braces as shown in the picture.
You can tighten the screws to lock these foot braces in place. (screws on the outside)
Position the other 2 foot braces as shown in the picture.
Screw the foot braces loosely to the cross-beams (screws on the outside).
These two foot braces should not be locked at this time, we need to keep a little flexibility to position the printer correctly later. We will lock them once the printer is installed.
Step 8.3 Mouting the squash ball foot braces to the Mk2 / Mk3 printer
Position the 4 foot braces on the lower cross-beams as shown.
The parts are identical but are placed differently: do not choose the wrong holes.
Screw the foot braces to the cross-beams (screws on the outside).
