knobby rc tire

thingiverse

I initially developed this as a test for my computer to manufacture a ring, only to discover it would print smoothly from the inside but leave the outside rough with a 0.5mm nozzle. The result is an RC motorcycle tire look-alike. I've placed it under the category RC because of its resemblance to a miniature tire, despite its small size - 25mm inner diameter and approximately 31mm outer diameter, without any central hub to speak of.
