After printing his push drill and assembling it I managed to break the jaws when tightening the chuck on a small drill bit. This meant I would have to print the largest part of the drill all over again since the jaws are fused to the body. This seemed unnecessary when I had broken such a small part, so I decided to make a slight improvement.
Instead I decided to split the body from the jaws so they were two separate parts. I made spikes on the bottom of the jaws so they would lock into the gaps between the screw thread under the chuck.
This worked well and drill bits of various sizes seem to still sit nice and centered.
Although the main purpose here was to split the jaws so it would be a quick print if they broke, I think this has also allowed the jaws to flex a bit more without breaking.
