Draft dog door mount

A very simple design to hold a draft dog against a door, without having to use screws or tape velcro to your door. I'll try to update this with a parametric design in the future so you can update it, based on your door style!

In my situation, the dog has a (squishy) diameter of 90-100mm and my door has a thickness of 39mm. The design is flexible however so it should fit all dimensions close to this one.

Update: parametric design added. First one ever so let me know if there are errors in it, I'm happy to have a look!

Small tips are welcome to keep the training going ^^
