I needed some small feet for a trophy I am making for a discgolf tournament. The trophy itself was made primarily from waste materials and other recycled parts and thus the feet also should be..

The first revision was made in OpenSCAD for last years trophy and a friend printed them in NinjaFlex for me. Came out nice, but he asked for a parametric version... which turned out to be a little tricky in OpenSCAD (the math.. it baffles me), so since I just started using Fusion 360 and had a pretty good idea how to do it.. well.. here it is :)

The included STL-file is for a foot that is 20mm wide at the widest point and a total or 12mm tall with a 2mm hole for a screw in the middle.

If you need other dimensions you can open the included Fusion project and change parameters to suit your need. The important parameters are 'totalheight' and 'topdia' which controls the total height of the foot and the diameter at the widest point.
It might be possible to change the chamfer for the screw hole (flat head screws don't need it). If requested, I can add that parameter.

Print settings depend on the printer and the material used.
If I would print this in PLA, and the feet didn't need to support much weight, I would probably just go with 0.8mm walls, 0.6mm top/bottom and 10-20% infill @ 0.2mm layer height.
