Training flap for CatMate/CloserPets cat door

Training door for CloserPets / CateMate cat door for glass panels. Ideal while your cat is still getting used to open the new flap. Swings freely, so it's much easier to open. 

Important! This door has a very loose fit and it's not wind proof. If you are looking for a air-tight replacement door, you will need to adjust the model and add some magnets on the bottom.

For faster printing, I include a “no fill” version. Just cut a cardboard to the right size and close the door with that. 

OpenSCAD file included so you can customize as you need.
