Anycubic Vyper spool holder

I updated the extruder to a direct drive and wanted to relocate the filament spool and remove the out of filament sensor. This is what I came up with, the roller partis from another members post. It fits a 1" PVC pipe inside and uses 608-ZZ bearings. These bearing have an 8 MM bore which is very close to a 5/16" bolt. I used a center punch and dimpled the 2 areas where the bearing are placed on the bolt. With light taps the bolt was fitted into the bearing which had the PVC pipe installed. The bearing mounts for the top bar on the Vyper were threaded with a 5/16-18 so the bolt can be screwed into the mount and a nut is used to tighten the bolt so it will not loosen. the mount fits the top bar on thee Vyper and it zip tided to hold it on. The holders are spaced apart, and the filament goes between the 2 mounts into the direct feed extruder
