eSun eBox Replacement Tray (with captive bearings)

This is a eSun eBox replacement base with 608 bearings placed onto the stock smooth rods. I based it on inks007's design that he in turn remixed from tgsparky77, so credit to both of them.

I redesigned this after installing inks007's design and having the shafts fall out of the bearings after about 10 minutes resulting in the spool collapsing to one side then my filament snapping.

The improvement with my remix is that the bearings are captive in a slot and the rods have no way of working
