I wanted some squash ball feet for my Ender 3, and wanted a victorian/steampunk kind of look, so I merged a bunch of ideas. I liked the way the squash ball feel looks better, but personally didn't like the movement of the printer, so I also created a set of feet that have a hard ball, to which I added felt pads underneath to minimize noise transfer.
I print these with the claws pointing up, without support. I do suggest printing with at least 25% infill. Printed one set with only 10% infill, but after a while could hear creaking that I didn't like.
If you print some for your printer, please post a make, I'd love to see what you choose.
print with talons pointing up so no support is needed.
