Weight rack

The bigger disks thickness is 19mm, its diameter is 180mm and the inside distance between the two disks is 150mmI've used 10% infill and so far it holds.The link should clip in the sides and hold itself even if you shake it a little.I could have printed the whole thing in one part but wanted to try linking two parts, and also the link is a small piece easy to adjust and print in case you need to adjust the total length of the rack
