Universal switchgear cabinet key

thingiverse

This key is my first 3D object made with openscad. I chose this for two reasons. It's a nice object to learn how to work with openscad. And more important: I think every geek, hacker, technician want to have this tool in their toolbox!!!! This key fits on a lot of cool things. I tested it with trafic lights and street lights but this will also work for For control cabinets, shut-off systems in gas, water and electricity supplies For technical installations in buildings like air-conditioning and ventilation systems, shut-off valves, mains switchboards etc. please post your results in the comments ;) Instructions This is just a replica of the key you see in the picture which is made in metal. If you want to print it in plastic (which i did) it may be not strong enough so you can size the diameter of the cylinders up (openscad) so you'll get a heavy duty model.
