4kg Filament Spool Roller

I needed a filament spool roller that operated smoothly with bearings for my dry box. I keep my 4kg carbon fiber nylon in the dry box until the spool is empty. This model fit the bill just needed it to be a little wider. I widened the base and spools to accommodate a 4kg spool. I printed the spools with 6 walls, the ends of the spool to the flared out part are 100% infill and the center section is at 25% infill. Base is also 6 walls and 25% infill. I'm sure its overkill but I don't want to deal with any failures.
