filament spool roller base whith no metal parts

P3steel style spool roller by toolson looks cool.
however the bearings i have are 608ZZ and i don't want to use metal parts if it is not necessary.
so i remixed it
1. short width frame. 628ZZ:8mm ->608ZZ:7mm
2. no metal screws, no nuts. i added 4.7mm shaft to the washer.

if you have 628 bearings and you just not want to use metal parts, print toolson's original frame and my remixed washer.

if the shaft doesn't fit well, heat the shaft and pinch it with pliers.
i feel happy if you post
