Prop adapter for 29mm outrunner

thingiverse

I snapped the shaft off my engine during a botched landing, so instead of junking the motor, I built a makeshift prop adapter that wraps around it, secured by a six mm bolt and some strategically placed 4mm nuts and bolts. The result was a surprisingly effective prop adapter. V2: My engine overheated, prompting me to install a turbine cooling system on the shrouded section, but I'm unsure if this made a difference since my engine continued to overheat and melted off.
