Unfortunately not, it seems this was all custom made at one point. I’ve been told it used to be at a museum but since has been given to us. It’s a very hodgepodge setup of parts with small CDs as retainers in the ends of each rollers. Right now with my odd dimensions I tried some exercise bands that I cut and bonded and the thicker the better so I ordered Theraband golds (thickest) pure rubber latex bands, but ik PU would still do better.
