Filament Wall Hanger

I printed this hanger for my wall. You can also print two of them and two connectors to leave it on a shelf without hanging. I use the 608-2RS Ball Bearings on each side with a 120 mm long rod from the MMU kit. The ball bearing is 8 mm inner diameter if you wanted to print a rod one for it. Or you could get one from amazon that would work, smaller than 8mm so it would be a little loose on the ball bearing. 608-2RS Ball Bearings – Bearing Steel and Double Rubber Sealed (8mm x 22mm x 7mm)304 Stainless Steel Rods 4mm x 120mm Solid Round Rods for DIY Crafts - 5pcs
