Parametric RC Airplane Wheels

thingiverse

I needed wheels for my RC airplane. OpenSCAD works perfectly with only 11 lines of code to make a resizable wheel. Of course, you could resize a wheel in your slicer, but then the axle size would change. Here you set whatever axle size you want and set one variable for the radius of the wheel. Everything else resizes according to the radius of the wheel. Wheels don't really have any treads, which makes them most appropriate for airplanes and not ground vehicles. Minimum size for the current design with a 4mm axle hole is about 15mm radius wheel -- adjusting the size of the cutouts for spokes could leave more material in the center for a smaller wheel. 8/5/19: I added a hub for some extra axle support.
