About this 3D model

There are 2 versions: Version: No mechanical parts no screws, just a base and 4 rollers to print. Wide and normal sizes. Bend the base a little to get the rollers on. 2. Version: Uses M5 hex screws ------------------------------- Update 9th Nov 2023 Some of you reported the rollers not being strong enough and friction too high. I added another version which has the base in 3 parts. This Version2 also requires 12 M5x15 mm hex screws. VER2.ZIP files contains 3mf, and stl files.
