3D Modelling, 3D Printing Magnetic Roloc holder October 14, 2022 With a small workshop, little improvements are very noticeable. With these it’s much easier to switch disks and everything is within my arms reach. I designed two versions; one for 2” discs and another longer one for 3” discs. The final result. The holders has a place right on the metal unit which holds all the pads and cutting disks. Everything is within arm’s reach by the welding table. Printing. Closeup. Neodymium magnets holds it in place.
