Simple screen net cat door

thingiverse

I have 2 cats with their own schedules, and being their butler isn't on my agenda. I designed this simple cat door to allow my cats to enter and leave the house freely without needing me to open a door or window. "The main problem with doors is the rigid requirement for a hole in the wall" Cutting a hole in your door is not an easy task and definitely not a decision I want to make. My main issue with leaving open windows are mosquitoes. Or more specifically, the ladies that come with them. This is how I came up with the simple solution to mount a 3D printed cat door on both sides of a mosquito net. Check out my project on instructibles for more details: https://www.instructables.com/id/Simple-Screen-Net-Cat-Door/ All you need to do is: 1. 3D print the door parts. 2. Attach them to a screen net and fasten with screws. 3. Cut the net between the two door frames. 4. Convince your cat to give it a try.
