The foundation comprises two threaded rods, each an M8, upon which rollers are inserted from a plastic tube with neck TG1232B, boasting an outside diameter of 32mm and an inside diameter of 29mm. The tube is cut to a precise length of 95mm, allowing for the attachment of printed rings on both sides, each featuring an 608 bearing with a diameter of 22mm, an inner diameter of 8mm, and a thickness of 7mm. Upon the threaded rod, the rollers are slid into place, accompanied by a flat washer situated between them. As the worms tend to bend, supports have been printed to provide additional stability. These supports are anchored to the upper shelf via M4 worms and are designed with three rolls in mind. The supports are specifically tailored for pitch 120mm M8 screws, ensuring a secure fit.
