Magnetic Screwdriver Key Cover

This quick-print tool is designed to snap securely onto keys with a 24 mm head diameter and 2 mm thickness. It features a slot for a 2 × 4 mm cylindrical magnet to keep the screwdriver bit firmly in place. PLA worked fine in my testing, but a stronger material is recommended for durability. The design is compact, easy to use, and lets you apply extra leverage using your key.
