The CNC 3018 Router uses Bakelite panels on it’s four sides. They weigh nothing and are just slightly stronger than cast acrylic. Want to mill/cut some aluminum? My 3/8″ Waterjet-Cut panels make your 3018 STOUT!!
These are precision cut and I install the two bearings. They fit the SainSmart 3018 the same as stock. I can’t say they will fit all other brands, but the couple I have inspected my panels fit.
