40mm RC motor heatsink (Large and Splits)

thingiverse

Acad file of a heat sink I designed specifically for my Neu-Castle 2200KV 1/8 scale motor is currently in progress. It's still in its un-machined state, with two distinct versions at this point. One version is intended as a single large heat sink, while the other is a more compact, mini design that allows for multiple units to be spaced apart effectively. My plan is to cut both versions and conduct a test to determine which setup yields better results in terms of heat dissipation. However, my current CNC spindle lacks sufficient power to handle even this task, so an upgrade will be necessary before I can proceed with cutting and testing the heat sinks. Once that's done, I'll upload images of the results, assuming I remember to do so – a prospect that seems unlikely at this point.
