Parametric Pottery Wheels

This is a parametric design for a Pottery wheel head. The smaller sizes can be used for banding wheels, or any other kind of revolving platform.

A plastic version isn't durable enough for pottery, so I've used the 3d printed wheel as a pattern for sand casting of metal. In this case I made the wheel from Aluminum.

For the CAD I have used Python Code to generate OpenSCAD code which can then output an STL file.

The larger wheels are bigger than my printer can handle so I have an option to print the wheel in pie segments which can be glued together.

I also have a core box model. A core is needed to prevent metal shrinkage in the central hub when the wheel is being cast.

The Python source files can be found here:

The files attached to this thing are specific instances of the OpenSCAD and STL output for an 8" wheel.

I don't expect too many people to cast their own wheels based on this pattern, but if you are in
