CIM motor gearbox

this is a quickie:
does anybody know where i can get the CIM motor gearbox and how much it costs? i mean the silver gearbox that has square ends that goes on the black CIM motors (im 98% sure they’re CIM motors…i mean the ones you usually use for driving)

that would be it :slight_smile:

By the way, AndyMark also sells a similar item with a 181:1 reduction, which might be useful if you’re designing an arm.
