3D printed mold guns

Ideally it needs to be 3D scanned to create the file, unfortunately that puts it beyond almost every hobbyist and I doubt if any company that has the equipment is likely to be bothered doing it.

I notice you have a Singer 331 K$, I was looking at this machine actually the K5 but wondered how you reduced the speed to a leather working  level, otherwise it looks a handy machine

OK found out the 331K6 and for smaller items the K4 are the leather machines so 5 is no good, but still needs reducing from 2200 rev

Chris, the only way to get good, controllable slow speed on an industrial machine is to fit a servo motor! I spent much time messing around with speed reducers, pulley sizes etc. on my first machine (51W59) trying to tame the clutch motor. When I finally bit the bullet and bought a servo I didn't hesitate with my other machines and just bought servos straight away. I also mess around with pulley reducers with the servo as it does help as well, but the servo is the only way to go (imo).

The 331K4 I have is basically a straight stitch garment machine, the only reason I have it is that it was free, just needed a bit of work to get it going.
