Key for Altelix 12x10x6 FRP Fiberglass NEMA 3X Box

Recently used the Altelix 12x10x6 FRP Fiberglass NEMA 3X Box for a project and noticed how flimsy the key was. Thought I'd try to model it so I'd be able to print out a replacement if needed. Very much a WORK-IN-PROGRESS project as this is the first version of the key and I have yet to print one. I have included the Sketchup .skp file to make it easier to modify.

As you can see the "key" is a pretty simple design and the lock on the box really just serves as a way to keep the door shut rat
