Drill Chuck up to 12mm
thingiverse
Resized to hold drills up to 12mm. Update: I added a hole in the jaws to insert a hot nail (PLA) or fill it with ABS glue or slurry to improve layer bonding. Update 2: I added "jaw_8-13mm_*" which works from 8 to 13.5mm (5/17" - 1/4") https://www.thingiverse.com/thing:2625085
