This is foot for tabletop placement of the RepRack Bearing Flange Roller filament spool holder.
Print orientation should be to print the large, flat surface of the foot down on your printer's bed.
I printed it in Sainsmart TPU (95 shore A) at 0.2mm layer height with a 0.4mm nozzle, 25% honeycomb infill. The GCode is for printing only one foot, but I added 15 instances and printed 16 at a time.
