Description
Hello everyone,
this is a model of self-centering 3-jaws lathe chuck. It's not designed according to any specification, just for illustrative purposes only. Spiral mechanism is based on bevel gears. I've also attached F3D files for customizing in Fusion 360.
Note: it's important to match jaw with foot according to numbers in brackets.
Time needed for printed: 35 hours (100% speed, nozzle 0.4mm).
