We have been experimenting with the common 608ZZ ball bearing to make cheaper V-Slot style maker wheels. In this Tinkercad file is an exploded view of the 608ZZ bearing and the 3D printed parts to covert the common bearing into a V-Slot maker wheel. Worth note these are larger in diameter than the standard V-Slot wheels so they will not work with the standard plates so that is next on the list to draft up a set of standard plates to use with these.
To print these, simply delete the bolt and bearing placing the remaining parts flat on the work plane.
