You will need 2 sets of prints (1 triangle piece and 2 spacers per set). Combine the parts as shown below. You will need to have the nuts facing toward the ground.

The triangular parts have holts that align with the holes on the top of the enclosure - add a set of fasteners on both sides to anchor them in place. Done!

What's with the arch?

The reason that we designed the arch into the Sumo Enclosure is because, with the CoreXY design, the Prusa XL spends the beginning of the print with the print bed all the way at the top of the printer. Without the arch, the view of the beginning layers, which are the most important, would be obstructed. By adding the arch, the visibility of the initial layers is improved, and the arch also fits the design of the Prusa XL as well.
