emmett, this gear bearing has been such an inspiration to me. These parts were made using your original design on customizer. Here's hoping to gear bearings getting to Mars someday!

NOTE: PRINT THE TREAD WITH NO TOP/BOTTOM LAYERS AND NO INFILL.

I used an extrusion width of 0.7 for perimeters and 0.67 for external perimeters. I used 2 perimeters. I used a 0.6mm nozzle, but you should be able to squeeze this much out of a 0.4 nozzle if you slow things down a bit. I used NinjaTek Cheetah for the prototype, it prints great but isn't grippy enough.
