Cube 3D printer community

I have. I actually finished this hack tonight and the feeder on my 2nd Gen Cube keeps jamming (slip-click-slip-click) because the 1.75mm filament is too thick. After disassembling the head unit, I've discovered that 3DS makes it very difficult to adjust the gap between the gear and the roller. All of the machined and pressed metal parts seem to be fit so that you can't adjust it.

I'm sure it can be done with some grinding (more than I've already done) as well as some parts purchased online but on the fly = no-go.

I'm researching a parts list to allow for creating a gap and I'll be sure to post it here when I finally get around completing it. 

Finding a filament manufacturer that extrudes or presses the filament closer to the tighter end of 1.70-1.75 would be nice but I've yet to find one that is reliable. Mostly because that's not what tolerances mean in manufacturing.
