YATW: Yet-another-toy-wheel (OpenSCAD)
by seedwire, published
An OpenSCAD model of a wheel, probably best suited for a toy truck, etc.
Model can be rendered for DualStrusion, too.
Requires the MCAD library. Also, the default OpenSCAD tree element limit prevents the OpenCSG library from rendering this in the quick view. It renders fine if you change that, e.g., to 8000. (Edit/Preferences/Advanced)
Adjust the OpenSCAD parameters to vary the wheel radius and width, number of vents, shaft diameter, and tread depth.
The default values create a wheel similar to those on a Tonka truck one of my kids have.
The top-level component has a single parameter to select between three models: 0=the whole wheel, -1=tread only, +1=hub only. This is useful for exporting the two pieces for dualstrusion.
update: slight modification to the hub- dualstrusion was continuing to be problematic, so I've added some ribs at the base to firm up the hub during the first 5mm of layers.
