spool holder for 80/20 aluminum extrusion(1" square)
thingiverse
I created a moisture-proofing box for five spools using a 74qt weather-tight container from ContainerStore.com. I needed a spool holder that would allow for effortless changing of spools inside the box, while also providing space for silica gel packets at the bottom. So, I designed my own spool holders inspired by a dual-bearing design found on Thingiverse. This custom design slides onto an 80-20 aluminum extrusion bar and can be securely held in place with just one screw. A 3mm screw is used to tighten the bearing into position. Tip: To get a free-rolling bearing, find the cheapest 608 bearing available on Amazon and then dip it in WD-40. This removes the thick grease completely, leaving you with a smooth-operating bearing.
