I wanted to try some string art and thought of the spokes of a bicycle wheel - so I made a simple bicycle around it. Quite simplified that is - there aren't even pedals; I tried some, but they didn't look good, so I left them out; no chance for a chain anyway :) But the spokes are in a realistic pattern! And the wheels can turn! 

Note that it easily falls over when standing (somewhat realistic, too…).

The 3mf file has the model split in different parts for easy coloring.

Print settings (important ones in bold):

• 0.2mm layer height
• random seams
• slicing gap losing radius: 0.0
• wall generator: Arachne
• 3 walls

If the wheels don't turn, try slightly negative XY size compensation (e.g. -0.02; OrcaSlicer: contour: -0.02, hole: +0.02)
