Doorstop (Fixed)

One of my first attempts at making something useful.
It's a fixed-size door stop, preventing my kitty from being stuck in a room.
The door thickness is assumed to be about 4cm.

UPDATE: I've recently added a more sturdy model - v2. I have no pictures of it, but the stl and blend file is included. This model consists of three parts rather than one. The "stops" are printed in a vertical position to give the model more strength, and I personally glued the stops to place with Tamiya Plastic Ceme
