Johnson card shuffler rollers

I bought a vintage Johnson card shuffler on ebay. It was really cool to have but the rubber rollers that move the cards were harder than a rock and spun on the shaft. I ekpt looking for a solution everywhere. Nothing. I bought some TPU for another project, and I thought, why don't I try printing them. I'm not really skilled with CAD and designing, but I fiddled my way through on Bambulab Studio. I sanded the surface a little to smooth the print and installed them. The shuffler has never worked so well. I hope this helps someone else!!
