Upgraded The Ultimate Spool Holder

This is an upgrade to the "TUSH" The Ultimate Spool Holder which allows usage of 608 bearings with a sleek simplistic design allowing you to feed your filament with very little resistance. I have upgraded this object by adding a fillet to the edge of the axle for the bearing support which allows for 100% easier installation of bearings and very little effort and no need for a vice. After breaking a few of the "TUSH" I felt that there was just one more thing that could be improved on this design.
