Customizer shaft collar

thingiverse

Say you have a gear spinning around a shaft. Printing the gear takes a long time and getting the shaft connection right is tough. It makes sense to print the bit next to the shaft separately, then screw it onto the gear. You might want to do the same. UPDATE 2019-01-08: A small adjust was added between the contact faces, along with a chamfer cut on the inside corner to get a better grip on the shaft inside the collar. You can see examples of this at: https://www.instagram.com/p/Bppv1YmhSMT/ https://www.instagram.com/p/BpqEr2XhSDU/ https://www.instagram.com/p/BppxjhUh2Ev/ https://www.instagram.com/p/BqBksYSH87E/ https://www.instagram.com/p/BqfdchRH_jM/ Customization options include: - the inner diameter (sane values less than outer diameter) - your printer adjustment (in case ID is overtightened) - opening cut angle in the collar - screw diameter - screw head diameter - screw head offset (distance from cut to the flat where the head sits) - number of nut sides (in case you want square nuts) - axial holes (0 or 2) and axial hole diameter. All other values are automatically generated. The part is labelled with the inner diameter, as two couplers side by side can be hard to tell apart. This design has been tested OK on a Prusa i3Mk3 from 5mm up to 1.315" dia with M2-M4 screws. Tag @imakerobots on Instagram when you print one - every +1 like helps!
