Spool Holder Upgrade

there are a lot of spool holders here on Thingiverse and many of them can be placed on top of the 3D printer. But not in my case because there is a little shelf above the printer that doesn't allow me to put it on the top. so i decide to upgrade the original Tronxy p802 spool holder and make it super easy to turn using well made bearings!
hope you like it!
