Unimat 3 Lathe CNC adaption

These models allow you to 3D print some mounts for NEMA 17 motors for your Unimat 3 lathe. I've then added 48 tooth GT2 pulleys to the NEMA and the Unimat leadscrews which both have 5mm diameter mounts. I then used a closed loop GT2 belt to connect the pulleys. I used a 280mm loop for the ways (Z axis) and a 216mm loop for the cross slide. I'm using a cheap grbl 1.1 woodpecker board for mine but I'll do a write up/video elsewhere about those approaches and then add the link back here. All the mounts use M3 hardware and I've used thermal inserts to make strong connections. As there shouldnt be any load on the drive belts it isn't critical that the clamp on mounts are totally rigid, therefore print in PLA, PETG or anything stiffish. I used a 60% infill to make stuff tough ish.
