This print is a clean replacement for a standard US 2-gang switch cover adding 3 sturdy hooks to hang your keys on. Dimensions are pictured, check first to make sure it will fit! In my home I've installed it next to the door into the garage.
I tweaked this design several times to maximize printability. It should be easily printable in PLA with 3 perimeters and 15% infill. I strongly recommend using a brim of at least 7.5mm as the sharp corners may tend to peel up. May also work well in PETG, but I did not have the right color in PETG.
