Hi, as I'm still looking for a key to the electrical box so I've created mine which I can print plenty of :D. There are all possible types of lock for technical cabinets ( electricity, gas, control cabinets, high voltage cabinets).  The handle is in two pieces which when folded are held by a m3x15 screw and a threaded insert for m3. If you don't have a threaded insert it shouldn't be a problem to just glue the screw in. The handle is so light that you can't even feel it in your pocket. I believe that every electrician and handyman will use this thing.
