This pinwheel was designed to mount on the side rail of a Thule Chariot stroller. I plan to design and upload a more generic adapter to work with more strollers. At normal walking speeds, the pinwheel will spin, providing extra entertainment for your little one on strolls.
The pinwheel was designed using Raul Bejarano's toroidal propeller generator: https://www.printables.com/model/407414-ultimate-toroidal-propeller-generator
I was able to print without supports. Will definitely need at least a brim to print the mount piece.
Depending on your print quality, you may have a hard time screwing the pylon into the mount. For speed, I printed at 0.28 layer height, which was fine for everything except the threads. It took a lot of force to screw together, I think a lower layer height would have helped.
I was able to press fit the pin into the pylon to hold the pinwheel in place. You may need to use a bit of glue if it comes out too loose for you.
After assembly, the mount clips onto the side rail of a Thule Chariot stroller the same way the shade cover does.
