These pads are an exact replica of the original rubber ones you can print for replacement. The original rubber pads are quite finicky to remove since they are glued to the printer. You could glue in the replacements too but it is not needed since the printer's weight is above.

The pads are best printed in TPU or another flexible filament.

Infill should be at least 10% but it doesn't matter too much, Layer height 0.2mm.
