The original plastic feet from my AOpen SFF Micro ATX desktop PC case have started to become brittle from sun yellowing and when one snapped, I made a close replacement in F360

I printed them at low quality/detail and the layer lines really show at the top of the protruding foot part. it's up to you if this bothers you enough to print at a higher quality but for me that was fine.

you want to maximize strength in the Z direction so use a straight vertical infil like grid, triangle or tri-hexagon. There are also internal vertical holes so that there are vertical wall shafts that go all the way through for added vertical strength.

Updated!

Foot V2 added which hopefully improves the clip and lowers the chance of the clip tab snapping off too easily.

Print Settings

Printer Brand:

Kingroon

Printer: 

Kingroon KP3S

Rafts:

No

Supports: 

No

Resolution:

whatever you want but 3 to 4 walls

Infill: 

15 - 20% with a vertical format

Filament: PLA (ABS or PETG will also be fine) Silver

Notes:

sit the model flat on the bed and it will print without supports. if you do use supports, be careful as cura tends to put them too close to the body and they get stuck. or if you want support for the cutout on the base, then add support blockers for the clips.

also, ideally you should try to anneal the print if possible as the clip part layers can snap easily. this might be a v2 fix!

How I Designed This

Straightforward F360 design: Take measurements, add them as parameters, draw the features on a sketch and extrude as necessary, tweaking and editing the sketch as necessary

One sketch with lots of parametric measurements

final result
