I think the design is nice but I wouldn't waste your time trying to print. I tried twice with a lot of issues. I have printed dozens of things without issue but this thing has multiple. Bridges require an almost perfect printer to complete, even with a well tuned printer I think it would fail. The bolt will print completely bonded to one of the main crossbars. 20% infill with .20 layers, & printed extremely slow , it still has more issues that it is worth. Some pieces printed with great quality, others were below poor quality and unacceptable. The design would be better printed separately and allowing us to assemble. There is another design that prints separately but requires metal hardware. A good design won't require extra purchases/hardware but at least that design is usable. Sorry for the poor review but this was a waste of 50 meters of material (2 separate prints).
