About this 3D model
Metzench designed an open 16mm saddle carriage for the Igus RJM-01-08 plastic linear bearing. The Igus bearings require a 16mm bushing to "squeeze" the ribbed bearing to 8mm tolerance. I modified the SCAD from Johann's original Rostock carriage to have a 16mm enclosed sleeve for holding the bearing. I should add that I am currently building a Johann's Rostock with 8mm rods, and hope to use these simple and cheap bearings instead of the loud and expensive metal ones. We'll see how it goes.
