A spanner for those who work in an arcade, fits the brass cabinet lock 22mm lock nut & smaller rear lock nut. May also fit filing cabinet locks etc. Is plenty strong enough for a quick fix, since most of the time this clamps through a glass door/window on a 2p pusher.

Ideal to keep on your keychain saving carrying heavy steel ones.

Suggest to print in PLA+ or tougher, but normal PLA is serviceable.

I used 3 walls, 22% infill, 5 top 5 bottom layers.
