Petamentor2 - Puller motor joint with flange

thingiverse

This is my attempt to resolve the issue with the motor shaft fitting into the puller. I have modified the extractor to support a flange that is fixed to the motor shaft, where I believe it will prevent wear, and with 4 x 50mm bolts. At the bottom of the extractor I placed 4 inserts where the screws are fixed. For those who, like me, suffer from this problem, I think it's a valid attempt that solves it, without the need to print other parts, reusing what we already have and while we wait for the new version of Petamentor 3. What you will need, in addition to printing the STL: 1x 6mm Flange 4x M3 x 50mm screws 4x M3 x 4mm inserts or 4x M3 nuts You can weld the insert to the bottom of the puller, or use the nuts. In my case I put both to make it stronger and give a finish.
