Hand Drill - large sizes

thingiverse

This redesigned object allows for adjustment through a single parameter controlling both the size of the bit holder and screw cap. However, additional customization to the handle may be necessary. The model includes unparametric templates for trimming the handle on smaller build surfaces or reshaping it for improved comfort. Note that the scad file requires stl files from the original design. To print, use full solidity without raft. The screw connection can be finicky; I recommend using plumber's tape to securely join the handle and bit holder, rendering the cap unnecessary. This solution worked well for me.
