Allen Key Handle M3

thingiverse

This handle provides a secure grip on an M3 Allen key, enabling users to apply more torque. To create this attachment, pause the print as it nears closing the slot for the Allen key. A square mark on the top right corner of the slot indicates when to stop the print. Insert the Allen key and resume printing. Alternatively, use a model version with support to keep the key from falling off during the print process.
