Filament holder craddle

thingiverse

I designed this filament holder as my first project. It incorporates four 604zz bearings and two 5/16 x 4" bolts. My goal was to create a system that allows for easy adjustments when working with spools of varying sizes. The bearings slide along the bolts, enabling the holder to accommodate different sized spools seamlessly. To secure the bearings in place, they are press-fitted onto the bolt. To print this filament holder, I recommend printing its sides upright and the bearing bra flat. This approach eliminates the need for any supports.
