This parametric doorstop is designed to look like a foot protruding under the door. The OpenSCAD file allows specifying the length of the wedge portion and the overall height. The intended usage is to have the top of the doorstop press up against the bottom of the door, but it could also be used as a conventional wedge. (In any case the height should be a bit taller than the gap under the door.)
This will work best if used on carpet or if printed in a flexible material. Just place the doorstop, press it down, and move the door on top of it.
Updated to include “foot plant.stl” from the model which was remixed, and adjusted the SCAD file accordingly so that this is easier to use. Please place these files in the same directory.
