Spur Gears

Note: This tutorial uses a 1.5mm module (tooth size) and 3.0mm clearance holes for M3 screws. The SUPERSPEED-660 has a larger kerf, and requires a 2.0mm module and 2.8mm clearance holes.

In Design Accelerator, choose to calculate Number of Teeth to keep the Ratio and Centre Distance fixed while changing the Module to 2.0mm.
