I lost the triangular key to my electrical box, which meant that I couldn't take a meter reading! On the back of this, I decided to model a handful of the most common utility keys and make a 3D printable version. Pretty simple to print, you can use a keychain, or piece of 550 Paracord to keep them all together. Printed using the ‘0.20mm Strength’ settings, takes ~1.15 Hours to print.
