This is a simple and straight forward enclosure/mount for a Duet3d Duet2 Wifi/Ethernet and Duex. Its modular so you can use it just with the Duet, or both Duet and Duex. This is a panel mount with cooling which gives you full access to the board + cooling under it. The boards sit flush to the top so the base where the cooling is needed is in the air stream. It works very well from some testing. Drops the MCU temp on the Duet2 10C in 15 - 20 seconds.
I designed this in an afternoon for a new custom printer I am designing to mount the electronics under the printer but keep them accessible for working on them in the future. Note you can follow the printer build - a large IDEX Direct Drive BCN3D style fully custom printer here: http://joekelly.co
I printed this in PETG at .2 layer height, 3/3/3 for walls/top/bottom.
There is a blanking plate for the fan holes (which are 3x 40x40 size)
