This is a model that replaces the original feet with adapters for 50mm Sorbothane hemispheres. Sorbothane is a synthetic viscoelastic urethane polymer used as a shock absorber and vibration damper. Sorbothane is incompatible with wood: sorbothane will deteriorate chemically from contact with wood. If you have a wooden platform for your printer, use a plastic sheet underneath, or a wax cloth (a kind of tablecloth) like I did.
Printing:
Doesn't need any super dense infill, I just used Generic PLA and 0.20mm Standard preset on QIDI Studio. Print "upside down", with the narrow portion down, enable supports.
Installation:
Just unscrew the original feet, one by one and replace with the printed model. The new model is pretty tight by design, so it needs a bit of force to press in, but shouldn't need excessive force. If you feel like your print needs too much force, either modify the model (FreeCAD document included), or widen the mounting center hole with a 7.5mm drill. Look at the photos for hints how to deal with it installation. Sorbothane is pretty sticky and should stick to the print at least for long enough to lift the printer in place, and the model has a small lip that should help keep the sorbothane hemispheres in place.
Once installed, run the input shaping to recalibrate the resonance profile of the printer, becase it's definitely changed from the profile with the original feet.
