Drill Chuck up to 12mm

thingiverse

This item is designed to accommodate drills up to 12 millimeters in size. Important update: I have incorporated a hole into the jaws of this device, allowing users to insert a hot nail made from PLA or fill it with ABS glue or slurry. This modification enhances layer adhesion. Further enhancements: A new version called "jaw_8-13mm_*" has been introduced, capable of accommodating drill sizes ranging from 8 to 13.5 millimeters (or approximately 5/17 inches to a quarter inch).
