eSun eBOX replacement base

Didn't like the way the spool roller (more like spool dragger) worked. So designed a replacement base that will hold the supplied 8mm rods in 4x 608 bearings. Rolls a lot better now. Need to replace the 2x M3 bolts with longer 10mm bolts. Make sure you use the existing metal plate under the printed part. I'm using PLA atm but will see if that will work after some time. PETG would most likely better a better choice.
