Enclosure for a Duet 2 Maestro that will fit either 3030 or 2020 profile extrusion, or without mounting hardware so you can do as you please.
This enclosure has a good standoff distance from the bottom, as well as vents located on the base and top and bottom walls to allow good convective airflow over the back of the controller (where the board is sinking the heat). This way it should be possible to enclose the maestro without the need for fans in most cases.
I tested this setup with 1400mA for X and Y, and 800mA on Z, E, and E2 without fans. The MCU temperature reads 40C with no overheat warnings after a 24 hour print. Keep the wiring neat inside the case though as excess could restrict some of the airflow.
You'll need 4x M3 bolts to secure the controller to the base, and 4x M3 bolts for the lid.
If your printing the 3030 or 2020 version, you'll want supports below the tabs only. Use support touching build plate only, and set support horizontal expansion to 0mm or Cura is going to add a messy wall along the perimeter.
Adding a bit more clearance between the mounts and the body
Added a cable port on the mount side (near the power port)
Rounded our the cables ports a bit
Adding larger vents to the base, to increase airflow
Adding a lid with cutouts for 12864 ribbon cables
Fix cutout sizing for 12864 lid
Fix placement of holes on the lids (to match the body)
Added lid with cutouts for paneldue with external SD card
