5mm Door dogging key/Allen Wrench

prusaprinters

5mm hex key/allen wrench for locking and unlocking or dogging and undogging pushbars on doors. At least that what I needed. Maybe you just need a 5mm allen key on a keychain. Who am I to judge. If you're using this for doors, there are various sizes so confirm what you need. I didn't need it very long and wanted it to blend in with the other keys on my keychain. The hex key part is only 35mm long which is roughly the size of a standard house key. This may also be useful for adjusting parks on a bicycle in an emergency. I printed it at 100% fill to give extra strength. 0.54g and about $0.03 YMV.
