If you are using flat belts, this seems to be a quick easy way to build guides to keep them in place. Each guide is a 3D-printed standoff with a small 3D printed roller that sits around it. Works great and doesn't require any machining other than drilling a rivet hole, as long as you have a frame member in a good location.

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

s_forbesIt 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.

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.
