thingiverse

Many individuals find the biohazard symbol appealing. The hex depth is sufficient to accommodate a washer between the gear and bearing, preventing any interference with protruding screws. In the provided .skp file, the hex head socket is intentionally oversized by 0.4mm, resulting in a slightly looser fit than anticipated but still functional well. The model was printed at a layer height of 0.2 and an infill rate of 0.4.
