What is that blue roller material? We've had some issues with our polycarbonate tubes flexing from the polycord.

It is a 6061 aluminum tube, 1.25" OD and 0.065" wall thickness. It's very stiff and lightweight, and it's just the right size to allow pressing a 1.125" OD bearing into the end. It is anodized blue from the manufacturer.

Re: pic: 3D printed belt guides

You can also keep the belts tracking by taking an O-ring and electrical taping it in place to act as a crown to keep the belt where you want it.

Or just actual tape, though our testing this year has shown that flat belting like this in the bottom of a hopper with a large mass of unconstrained balls on top of it very easily derails.

Second, just a couple wraps of electrical tape directly under where you want the belt to sit works perfectly

We haven't had issues with it, but apparently you have so I guess it depends on setup
