Adam, I just watched these again. I didn't actually watch more than the WCD stuff last December since I wasn't overly involved with overall design. This is Grade A stuff. Attached is how the design sketches worked in 2012 for ball flow through the robot for us (this wasn't our production design).

Since I'm going to CAD quite a bit more this season, it was a good brush up on a lot of the tricks and techniques I'd forgotten since I haven't CAD'ed FRC in 20 months (ha).

A word of caution about mirroring across or centering on a 'top' plane - some 3D printing STL > gcode programs, like Slic3r, cannot handle that and will slice off the bottom half of the part.
