Very Sturdy Wall Filament Spool Mount

I didn't like the additional weight of side spool mounts shaking on my Anycubic Kobra S1 so I created a wall mounted solution to be mounted nearby and hold heavier spools. This model features a removable spool stop so that spools with smaller inner diameter holes to be mounted with ease. Uses 4 screws to mount to the wall. Designed to use 608 bearings but functions well with no bearings in place. Print in orientation shown in photo. Layer height < 0.2mm with >20% infill. Print the roller vertically with normal manual supports underneath. Print the spool stop vertically with a brim.
