Pet Door for Window

thingiverse

I designed a functional pet door using a piece of plywood and some printed parts that my cat loved! Living in an apartment with no sliding glass door made it impossible to put a pet door insert in, so I created this solution. I split the design to fit on my printer, making sure the front and back of the frame were identical. Two sets of the frame sandwiched the plywood together. This pet door frame can handle 1/2 inch of material.
