This is a control / baseline model that I designed. It is intended as a reference model for some models that I will be building in the future. I Plan to explore the works of Johan Besler, and need a model to provide a reference point.

The model houses two 608Z bearings. It is held together with self tapping screws, and takes about 5min. to assemble.

Here is a link for the screws that I used:

The bearings are common skateboard or roller blade bearings

Simple clean up of the print is needed in the collet area of the disk, (depending upon on how clean your print is)

I designed these parts in FreeCad, and have included the FreeCad files for experimentation / modification.

The shaft I used was cut out of a compressed gas lift cylinder. The kind used to lift up the back glass and hoods of American cars. I found it at a wrecking yard. The diameter of it is a little less than 8mm. Typically there are three basic diameters used in most American cars.
