Telescope Mount Adapter Ring

I needed to create a ring support system for my skywatcher ed102 telescope in order for it to be mounted on a goto motor. The ring is a repeated print so 4 of them are screwed together with a m3.5 threaded screws and nuts.
They go into a rectangular extruded aluminum tubing, 20mm X 32mm x 2mm that were bought at the local hardware store in 1 mt pieces.
