3KU delta vibration dampener feet

My printer is on a desk and it amplified the noise from the printer so much that I could not even bear being in the same room when printing.

I printed lukeazadee's "Spring based anti-vibration feet" and used it for quite some time, but I had two problems with it: is not wide enough for this printer, and they slip out when I move the printer around the table.

Inspired by his design I made these.
