Key Holder with shelf

Saw this design https://www.thingiverse.com/thing:993883 made by Gerardorl and wanted to give it a go making it while learning how to use Onshape. Turned out really nice so I thought I'd post it.

My design is a little more simple, though it's just what I needed

Print this back side down (should import like that in the slicer you use) with no raft and no supports. I printed in 20 percent infill and used double sided tape (a heavy duty one) to adhere to the wall
