Model for replacement feet for a shoebox-style Comptometer. I.e. all the copper-colored machines, models A through to J. The original feet are invariably gone or flat, these replacements should snap right into the holes in the baseplate. Four feet per machine.

Recommended settings:
  material: TPU, i.e. rubber-like so Shore 90 or thereabouts, not the "AMS capable" variants.
  layerheight: 0.15 mm
  top and bottom surfaces: concentric
  outer walls: 3 

Note that the model has internal cavities - with the walls generated by the slicer, these ensure the feet have strength to take they weight of the machine. The rubber ensures grip and makes it possible to snap them in-place.
