Cat door with Simon's cat decor. The opening is 16cm wide and 20cm tall (164x204mm opening to cut on the door). The modeled frame is for 37mm thick door.
The parts are mounted with 3mm diameter screws. (Heads can be painted to hide.)
The small insets into the frame are glued to avoid color change or supports.
Door is hinged with a piece of wire (the hole is designed 1.85mm diameter - 1.5mm2 copper wire is suitable)
Each piece fits on a printbed ≥256x256mm
The author remixed this model.
Incorporated the decor into a functional cat door.
