T-handle for a 4 mm hex key
The 4 mm key fits M5 cap screws, which hold a lot of aluminium extrusion frames together. A T-handle spins them in fast, and the crossbar gives enough grip for the last turn.

Printing
- Prints as exported with no supports: T-handles and grips standing on the face the key goes into.
