A true maker is about integrating and repurposing. If the D-bore pinion gears just won’t fit your motor or axle that you’ve chosen to use in your project, check out these 6mm round bore gears.This 20 tooth, MOD 0.8 gear will mate with any MOD 0.8 gear but when building on pattern; the most common partner for this gear is a 100 tooth hub gear. This combo will create a 5:1 ratio, underdrive or overdrive depending on whether you’re set out to increase the speed or maximize torque.
