E are the ones I use Ducky. I like them a lot, although I’d like to find or make something a bit wider…easy enough to print, I suppose. Maybe I’ll work on that…or maybe one of the other 3D print hounds has already had a go at it?
Printing it shouldn't be an issue and canibalising one should be cheap enough to get the mechanics correct for expansion movement...
However, I can see an issue with getting the width and circumference of the sanding belts before you start venturing into the too big territory.

If your first cut is too short... Take the second cut from the longer end... LBD
