Step 1 Feet assembly
These pictures are from PrusaBox parts, but ModularBow parts are assembled the same way.
These two feet are rear feet.
These two are front feet.
These feet are an old version. There are no holes anymore to screw together feet and Spool tank
Using Prusabox’s screws, assemble the rear feet.
Assemble front feet with M4 screws.
