My new design.
More compact and built to use a 40mm 5v fan.
Stands vertically and has air vents and all ports facing the rear.
The front is left minimal with only one opening for the IR/LED and on top you have your Power/Function/Reset buttons.
I printed this out of ABS as its what I had on hand but I would recommend PETG.
As for supports I used A LOT but only because I printed mine in the upright position to retain a uniform surface on all visible faces.
