My prewife invented a way to hold a door partly open. It involved shoes that I trip over in the middle of the night. So, I designed and made this little gadget to slip under the door and hold it in place. It works quite well!

The outside diameter is 3.5”, and the inside slot is 1.5” wide. The floor of the slot is angled to ensure a snug fit.

I made this on my little CNC router. If you’d like the .stl file to make your own personal doorstopper thingy, it’s here: http://www.thingiverse.com/thing:6731

... if you do make one, upload it here or on thingiverse… I’d love to see someone else’s!

Thanks for looking!
