1:14 RC Tracked Conveyor

That's really not a bad price, when I was looking for U.S. suppliers the 50mm stuff was about $5/foot. You only need a couple of degrees of crown on the rollers. If you've got solid rollers, just turn a shallow taper on each end and leave a small flat section in the middle. It seems counter-intuitive, but the belt will track to the high side - that's how the crown works.

If you don't like the green color of the belt, vinyl upholstery dyes are available at a lot of auto parts locations. I've seen prices from $11, to over $30 per spray bomb. 40 some years ago I changed the headliner color on my '57 Ranch Wagon using that, worked like a charm and only took 2 cans.
