Cat flap for net door

This is a flap door that can be placed on nets for cats to be able to get out (can be used for small dogs as well). Includes locking pin to stop the flap from opening (optional to print).

Required hardware: 8 pcs M3x12 mm (or longer) bolts and 8 pcs of M3 nuts (self locking or not).

Requires 220mm printing bed.

I have tested it with PETG and it works fine. No supports needed for the printing.
