On this #freecadfriday, I finally got around to designing a paper towel roll holder for the stand I use in front of my bike that’s attached to the stationary trainer. For probably a year, I’ve wanted this so that I could blow my nose or mop up sweat off the bike, etc…
I took inspiration from a few other designs I saw around the internet. The hardest part was getting the thickness of the curved beam spring to provide the right amount of tension against the roll. It took me 3 iterations to get it just right. I effectively decreased the stiffness by 50% with each iteration, but I had no idea what would “feel” right to begin with.
A little #3dprinting, a little hardware, and a piece of PVC pipe I had around to make the spindle. We’re in business.
