Sound dampening feets for Ultimaker 2 & 3

These feet use 50 durometer, 30 and 40mm half-spheres made out of the visco-elastic urethane rubber "Sorbothane" to reduce the amount of conducted vibrations by a lot, without the problems of self-induced oscillation of more springy solutions.

The front uses 30mm half-spheres, whereas the rear uses the 40mm half-spheres. This is because the Ultimakers are a bit back-heavy and the Sorbothane half-spheres need a certain amount of loading to perform well, so this makes it sit level and matches the load to the Sorbothane optimal range.

They work extremely well compared to most other solutions I have tried through the years and do make the printer appear much more silent than before.

I bought my Sorbothane 50 durometer half-spheres (two 30mm and two 40mm needed per printer) from the seller "soundupgrade" on eBay.
