Fairy Door

thingiverse

several versions for different end goals, I made mine with a hinge that I picked up at a hardware store such that the door can be opened. I've also included files for a door that doesn't open. You'll might want to scale it up, I printed mine at 150% scale because I wanted the door to open with a hinge, if you don't want that then I suppose any size door will work just as well.
