This system is currently based on M2.5 bolts in the 5-8mm range. No supports are needed, just pick the most suitable orientation. Mounts and the rest are printed with 0.4 nozzle and 0.200 height.

Slow the print down after 100mm to prevent toppling. You might need a raft if your bed axis are very aggressive. Print one at a time for best plastic adhesion, I typically print about 150mm in about an hour. I print them with a 0.75 nozzle and 0.400 height. This is a prototyping kit for building desktop machines.Ġ.4 for Extrusion and 0.2 for the rest Infill:Įxtrusions should be printed upright, You can scale along Z axis to create longer or shorter extrusions.
