Summary

It has just been fun working with this FreeCAD. I had a bunch of these NUC boards and no cases so I made some. I had to modify my printer and fake it out to get the higher temps for the PETG but it worked pretty good
I just added grills for the cooling.
FYI the hole for the power switch is for a E-Switch LP1OA1AG Switch Push Button .
You can get them from DigiKey or Amazon. I picked blue LED there are several other colors.

Fixed the grill print
