Keyhole and handle cover with pushfit connectors (no screws required)

I needed lots of keyhole covers and door handle covers after we purchased new doors for the house a few years back. I printed these and didn't think about it much until the first one broke 3 years later. Not too shabby, the mechanics aren't very tolerant and break fairly easily but they don't get very rough handling when mounted on a door.

I wrote the openscad code 3 years ago, so it's probably ugly. But the design works.
