CAT DOOR – Push-Only Design – 2 mm Axle

Wind-resistant, draft-proof cat door (cat flap) for installation in doors or walls. The cat must actively push the flap to go through – both entering and exiting. No free-swinging motion.

Main Advantages:

• Push action required in both directions → prevents wind from blowing the flap open
• Superior sealing against drafts, cold air, and wind when closed (tight frame contact + gravity assist)
• The flap assembly consists of 3 printed parts for easy assembly and robustness

Axle: Standard 2 mm bicycle spoke, steel rod, or any sturdy 2 mm diameter wire/rod.

Print Notes:

• No supports required
• Material: PLA

Enjoy printing – and let your cat discover the push! 🐱
