Door Holder

Our basement door is on spring hinges to close automatically. Sometimes we want to prop it open just enough that the pets can open it and get through. This makes that easy.

The tolerances are pretty tight so I had to some sanding on the rails to get it to move well. Also, the knob was added after the fact but it would be pretty easy to add that into the model if anyone is interested.

The .scad file is attached for you to play with as you desire.
