Hi everyone! This is a design for a 3D printable shaft collar that we think will be useful for prototyping on a budget. It uses M3 screws as we are an Australian team, so if you are interested in an imperial version I will be happy to make that modification.
This was printed on a Prusa i3 Mk3 with silver Prusa PLA, standard 0.2mm layer height profile with 20% infill. These shouldn’t crack from the screws being tightened. We have yet to test this design on mechanisms but we plan on trialling these during build season.
