Tricycle
thingiverse
I created this prop for use. I've already tested it in both Cura and PrusaSlicer, and it's quite large - scale it down as desired. The model includes both obj and stl files, so you can easily adjust it to your liking. As for printing the actual item, I don't have a 3D printer yet, but I'm currently shopping around for one.
