Thanks to the great original design I was able to optimise it slightly and create an extended magnetic mount to suit my needs. For detailed instructions please see the original design.
Key changes:
Reduced the overall thickness of the DDU by 2 mm
Thickened the backing plate by 1 mm
Removed the center cable holder, as it was getting in the way of my cable management
Use this square USB-C female connector and mounted it on the back for a cleaner look
Made the LED support solid and removed the upper heat grille, as I found it unnecessary and difficult to print cleanly
Updated the TPU screen gasket size and thickness
Added an extended magnetic mounting bracket for my Fanatec DD1 and triple 27" monitor setup (uses six 15×3 mm magnets)
Added four M3 thumb screws for bracket mounting on the back
