This is a quick and dirty union of x-blunt-plate_1off.stl and x-motor-end-clamp_1off.stl with my pulley extenders so that these parts can be printed and used without modification. I also fixed the motor mounting holes that didn't go all the way through. These are intended to replace the existing pieces in the next set of production files.

About your extension brackets: Both could have a little more plastic around them. The tension of the belt can create problems that the bracket deforms a little bit. The bearings not being completely horizontal causes excessive rubbing against the mudguard washers.

Those should be idler pulleys on the bearings instead, don't you agree? The belts run awful, it works but barely.

I made one, but I still can't print. You wanna test it? http://www.thingiverse.com/thing:3970http://www.thingiverse.com/thi...

Parametric idler pulley

Yeah, I haven't actually tried these myself, my sheet metal version of the extenders works great. Spacexula (below) is building one with this version, though.

But yes, they definitely should be idler pulleys. In fact, running the belt all the way around the bars, though cool, is unnecessary, and you could reduce the parts by running the belt directly from the driven pulley to a single idler on the opposite end.

If I do the next production files I will include these. I am going to update the production files once I get mine printing, which might be next week.
