A hole cutting saw drill set was purchased to make sockets for the spoked hubs. The purpose was to make a 5" (127mm) diameter hole in each gear then use short screws to attach the two. Both pieces of plastic could be painted as long as the bearing socket was not contaminated.
Sizes didn't match the saw diameter and the hub diameter. The hole saw was less than five inches while the hub was more than five inches. Since the size of the hub was adjustable, easily, that will be changed in the next print.
In order to utilize the print hub, a comically large arrow was cut from scrap wood. This spinner could be used for a fun project like a random task selector or a carnival fun wheel. Its purpose was to perform an install with the available parts. A hole was cut with the hole saw then sanded to size as well as possible with a spindle sander. Several problems with the hub were found, which should be easily correctable. These problems wouldn't have been found without the mock installation.
