One of my favorite filament brands decided to change their spool reals from carton, but unfortunately the spool didn't roll great on my Lack side holder I designed while ago and was creating too much friction.

I made a new spool holder with 608 bearings, I was lazy and grab the mount from fifloaks design and modified it.

I only had 90mm long M8 bolts, so it is little to short but glued it with superglue and it works, but for the 80mm roller you need 100mm M8 bolt.

You need two 608 bearings and: 100mm M8 bolt for 80mm roller 110mm M8 bolt for 90mm roller 120mm M8 bolt for 100mm roller

You decide which length roller you need to print, use supports with the rollers.Keep the infill little high for strength.
