PC Case Foot Screw Attachment
Simple PC Case foot.
I made it a little thick where the screw attaches (3mm IIRC), so you might need a longer screw. It is for 6/32 sized screws.
You can adjust the size in Cura or your slicer. Cura also lets you sink it into the bed to make the bottom thinner where the screw goes through.
It is 24mm across. and 14.5mm tall. You can easily scale it to fit what you need in the Slicer, no need for any modeling tools.
Settings:
For holding up heavy things: add walls, 4-5; use triangle or some other infill, 60% or higher.
Use it if you like, just a quick replacement part for me.
