3d printed multiple reduction rear RC drive

Not sure if this guy is on here or not.. but anyway, this is one of the coolest things i've seen in a while.

Yeah, if he had started at endless sphere, it would have saved him at least two of the development versions...

I saw this earlier and thought this was kind of an odd design because the motors vents end up being covered. If you're going to use 2 motors to get more power, it seems counterproductive to make them worse at cooling.

If you look at that guy's youtube channel, he's done a version 4 of his ebike design now. The new design looks much better, but is no longer entirely 3D printed.

No kidding. Kind of sad to see people stumble through things when all the information he needs is tucked in here somewhere.

Looks like his v4 is pretty similar to a recumpence drive.

Love the giant 3d printed pulley. Makes me wonder how well a printed chain sprocket would work. #35 nylon sprockets are readily available and the composite "extron" kart sprockets seem to work well too.
