I purchased the Bambu P1P ARC enclosure and was so impressed with it that when they produced the SUMO for the Prusa XL, I had to get it. You must have an enclosure to successfully print high temp plastics like ABS, PETG and Nylons. I think I'm one of the first to have it assembled and working. I gave feedback and I think they will implement in the instructions.
The kit contains all of the hardware and lots of spares in case you drop of loose any. The instructions are great and they Joseph is very responsive.

I have no business relationship with them, just appreciate their products and a small business that makes good stuff
