I've added an additional F3D and STL file for a minor improvement of rounding off some of the sharp edges. Should make it more family friendly if putting it in high traffic areas!

Needed a catch doorstop but didn't want to mess around with springs or bands. Designed in F360 to be single piece print, attach to any flat surface.

This doorstop will catch the door when open and can be released with a foot or hand via the spring mechanism.

Default door width was 35mm.

You can adjust the infill density to make it more / less springy. I found 60% infill a good mix of springiness and resistance.

Does not require supports or rafts etc.

To install I just held on the door while open and screw the right hand screw in, then level and screw the left hand in.

F3D file included for remixes and adjusting the door width.
