Mini hex / imbus 6 mm (keychain)

Although PLA is not an ideal material for tools, this little guy is suitable enough to serve e.g., as an occasional / emergency locker door opener, even if made of PLA. 100% infill is recommended.

However, use this tool carefully and never try to loose a rigid screw or anything else with force. There is a real risk that broken parts could remain in the hole.

How to use it: grip it with two fingers by the corner part and slowly turn.
