Designed these for a makeshift turntable isolation platform (using IKEA Lämplig cutting board). The feet house cut-in-half squashballs.

There's .5mm clearance in the XY-direction, so dimensional accuracy of your printer shouldn't be of concern. For me at least, the parts are still snug enough.

Required hardware (per foot):

-4x mounting screws (3mm in diameter, with a countersunk head)

-1x M8 nut

-1x M8 bolt - I used a M8x20, but for a lower ride height and for decreasing stress on the feet, I would recommend nothing longer than 15mm

-Half a squash ball - I went with a double yellow dot one (super soft)

-Fast curing glue

Assembly:

• Insert the M8 bolt into "foot.stl" and place "foot-lid.stl" on top (making sure they seat together properly), with a generous amount of glue in between. Clamp together, either with some clamps or with the M8 nut.

-Insert nut into "mounting-flange.stl" and screw to the surface of choice.

-Cut squashball in half (along the seam). With a generous amount of glue applied to the bottom of the foot, push the ball firmly in place. You might need to hold it for a while.

-I recommend printing "spacer.stl" for a little bit more range of adjustment. Just sandwitch the spacer between the flange and mounting surface. Thickness of the spacer can be adjusted in your slicer, 3-5mm should be adequate for most applications.

Orient "foot.stl" with the hexagonal hole downwards. Other parts with flattest side down.
