Needed some rubber feet for the Flashforge Dreamer printer. Print this (x4) in SemiFlex (preferred) or NinjaFlex.

Print with about 4 shells and 25% infill. SemiFlex or Zentoolworks Flex seems to work better than NinjaFlex. You may have to scale down to 90-94% if it is a tad too long (originally tried with ninjaflex which squeezes in a little easier). I may upload a second version with a better fit later after I get a chance to look into it.

90 is perfect for me. 0.25 layer, 4 shells, 25% infill, 230c, 50c printed at 30mm/s
