This case for the Duet Wifi is a simple version that retains the under board cooling that Ocie's Box has. It also has a hinged top to make it quick and easy to get at the board. The top can also hold a 82mm fan if needed. So far I am not using the large fan. Just using the small under board cooling 40mm fan.
3mm screws and locknuts were used for the hinges. 3mm screws were used to mount the base to the printer from the back side using of the same holes that hold the duet wifi to the base.
Added a step file that has the complete assembly for anyone that may want to make changes.
Printed in abs. Other materials should work fine.
