I printed all of these flat on their faces except for the shelf variant. I printed that on it's back (The recessed area) and used supports for faces only touching the build plate.

I spent probably too long trying to make these things with dimensional accuracy but these were also one of my first self-tests for such a use case.

you know when you plug something in and the darn thing starts sagging down and falls out of the outlet? yeah i hate that too so here you go. I made this outlet cover with a shelf a few years ago and since then the bathroom has been renovated. A new outlet was put in place of the old one so I'm sorry i don't have any images of that one in use.

Then there's just two other outlet covers I needed. A dual, which was used to make the shelf variant and the more ubiquitous square switch/outlet cover. I hope these are useful to you. share em around and let people know i made them... or not.
