Push/pump drill (replaceable jaws) collet

thingiverse

I loved LindsayTCrawford's remixed drill design, but unfortunately, it couldn't hold onto the bit securely enough to prevent slipping. To improve the grip, I designed a custom collet that fits snugly within the head of the drill, providing a much better fit for the bit. However, you'll need to modify the file for each size tool you want to use with this setup. To get started, download the files from thingiverse.com and replace the chuck_jaws component with my custom part. Printing it upside down yields the best results.
