Made a case for the Duet 0.8.5.
Printing latest design now (image 4), getting ready for public release. Wish I had a Duet WiFi to make a case for, hope to get one for MiltyKoss Unit 2.
Case has 2 40mm fans and airflow for the drivers and cpu factored into wire pathing, which is all out the bottom.
Airflow is good top and bottom of PCB

Very nice design 
So funny thing happened when printing the latest design, at 80% I decided to get clever and reposition a fan cooling the extruder driver, bumped a carriage and made it skip steps 
not cutting and reloading the gcode at the error, got enough print to see where some CAD needs changing anyway. But having that last 20% of the prototype would have been nice… DOH!
Dammit…, couldn’t you post this earlier ? I am just now finishing printing my own “in a hurry” designed case for the 0.8.5… yours looks absolutely great !
@Romeo_Pavel It will be on Thingiverse in a day or less, I made many prototypes, I really need a recycle and re extrude filament setup
It is stackable using hex head screws with the round tall cap (the standard kind). Wiring goes out bottom and then out side slots between frame that holds Duet PCB and the bottom panel that can be mounted on rails or wherever with a hole pattern on the bottom. Final version has slots for mounting adjustment instead of holes, other little fixes and features like that to make it on par with server rack mounts etc as far as usability, cooling, positioning, accessing wiring, etc.
I trained as an industrial designer but before that did many random things including network technician at a major hardware manufacturers router lab. Also a ton of modding PC’s and overclocking with water cooling. Trying to apply all that as stepper drivers need more heat removal than the 3d community really pays attention to, I suspect, sorta new still. In benchmarking competitively on an E8600 (4.5ghz 24/7 stable for 2 years, triple water loops CPU GPU RAM) calculation precision degrades enormously with overheating. I dont know for sure on a 32 bit duet, the controller chips are more robust for one, but I suspect that it can only help to give the drivers and cpu top level air cooling design.
