Motor Gear 25 Remixed

This is a modified version of the 4-bolt drive gear from the fabulous powered spool winder model by @Damian27 . I had a ‘sticky’ spool when using the winder, and have tried to make a drive gear that has a mechanical ‘grab’ to the motor shaft, by use of rearranging the bolt holes and adding a threaded hole for a ‘grub’ screw on to the flat of the motor shaft. The gear remains the same to make, with the addition of 2 extra M3 Heat Threaded Inserts, and extra M3 16mm for the face and a M3 12mm or similar for the grub screw. I printed with 6 wall loops, 0.2 layer height, and 100% infill in ABS on my Bambu Labs Carbon X1. I've made all the bolt holes a little tighter than needed, so I could easy them out to the needed diameter with a hand drill.
