thingiverse

To assemble the system, you'll need to secure an M10x110 screw with an optional imbus feature using a square screw nut and connect it to approximately 100 millimeters of polypropylene (PP) pipe that's 20 millimeters in diameter. You can add additional pipes up to 32 millimeters in diameter, but they should not exceed the original 20 millimeter diameter. To make clean cuts on the pipe, use a template specifically designed for cutting at a 90-degree angle.
