A2212 Brushless DC Gearbox

thingiverse

A2212 Gearbox with 9:1 ratio. Works pretty good, there is no significant heat generated even though it generates really annoying sound (not that loud, but annoying). You can find more information about how to assemble and modify the shaft of your 2212 motor on the original post : https://www.thingiverse.com/thing:4698862 I edited : 1. All of the bearing slots so it fits the one that I have lying around (605zz) 2. Output shaft hole diameter to 5mm 3. Middle shaft hole along with its shaft so you can 3dprint it without worrying the shaft will break since there is no significant weight so 3d printed shaft will enough. 4. Slice the Frame so you can print with fewer materials. (Thick version still available)
