The width is non standard. Its deigned to fit on a 220x220 build plate.
I used glue to assemble the top and main case.
The top has room for mounting a 120mm fan
The inside of the DOORV2 has a small hole where a 8mm magnet can be mounted. I use this together with a bolt mounted on the main cases mounting holes(top right) to get a nice "click" when I close the door.
I printed it in PLA, but I think PETG would be a better option.
