I have always been annoyed by the size of electrical panel keys. In my line of work, I need one with relative frequency. However, keys that come with panels are much too large for a key ring. This design aims to remedy that problem.

I have been surprised at the strength of the key, but a seized panel can warp the plastic if you're not careful. Luckily you can print a few spares in a matter of minutes!

I recommend printing this at 100% infill at the smallest layer height you can for maximum strength.

Those look great! We don't use those types, but if I come across one, I'll be sure to print it.

Those panel keys make great bottle openers also. Have you used this design much at all? Some of our panels at work can be a bear to open.

I used it around a dozen times yesterday. Yes, some panels are much harder than others, but if you plant a firm palm pushing in on the door while turning it can help a lot. On the toughest panels, a key this small can hurt if you're not using gloves, but without this key on my ring, I'll too often resort to a flat-head screwdriver, and end up damaging the lock.

As far as the bottle opener goes, I had at one point considered it, but I'm fairly certain that would affect the structural integrity of the already thin print.

Thanks for the response!

I meant the metal key. Pushing on the doors helps some, but not always.
