I lost the chuck key for my wood lathe chuck. I made this one to use temporarily until the replacement arrives. It wont hold up to heavy use, but for turning pens and other small jobs, it should be ok.
To minimize printing time, I made this to fit on the end of a 3/8" drive ratchet.
Print at 100% infill. Orient so that the ratchet connection is down and the pivot pin is up.
I printed in ASA but other filaments should work too.
The author marked this model as their own original creation.
