3D Maker Parts MGN9C-1R-150 Linear Rails with Carriages

Stainless steel rails for your smol printer. These are Black Stainless Steel (not carbon steel, this is way better) that goes through electrophoresis to add a wear resistant black coating on them. Rails will be firm as they are our heaviest pre-load, but smooth. These may come pre-lubed with Mobilux EP2.If so, to finish preparation, use a small tipped device to remove any grease from the rail hole, and then spread it evenly around the rest of the rail using proper rubber gloves. Set the rail on a flat surface, and with light pressure on the carriage move it back and forth a couple dozen times. That's it!
