(1) Gear diameter calculation formula: Gear outer diameter (tooth top circle) = (number of teeth + 2) * module
(2) If it is a 2mm axle, for a tight fit gear, please select a 1.9mm hole gear; for a loose fit gear, which can slide freely, please select a 2.05mm hole gear. In other words, for a tight fit, choose a gear with a hole 0.1mm smaller, and for a loose fit, choose a gear with a hole 0.05mm larger.
