The toonie has these little hubs that are the exact diameter of size A bearings, but they’re just too short for hubstacks. However they do have a use, they’re for finger spin hubs. So making them taller would render the finger spin hubs useless. Anyways, any ideas on adding the hubstacks? If someone can give me a method that would save the finger spin hubs as well, that’d be really awesome.
