Cat Door

A cat door that I made over a year now and finally decided to upload.

I use magnets to keep the door from blowing open in the wind(magnets on door and frame), i believe the magnet hole is 20mm but ive just been using some 10mm ones i had around.... one on each side of plastic keeps them from falling off

If i remember correctly you want frame and door opposite polarities for them to lock together

I also had to use a small drill bit and pliers to make the hole a bit bigger for the 6-32 s
