This is a case for the QuinLed Dig-Uno. It's not the first 3D printed case for this awesome LED controller, but this one has multiple holes for the external antenna for flexiblility in your install. It has mounts to screw the case to some sort of wooden structure. It has a snap fit lid with a satisfying click. It has honeycomb vents in the top. We used these in the school play this year and the effect was pretty cool. We had 8 WLED controllers going with the other stage lights controller through DMX software. I can't say enough good things about WLED.

The dig-uno board needs M2X6mm screws to affix it into the case. 

Light duty screws - M6 or M8 screws will fit the external mounting holes.
I'd print in PETG since PLA is flammable. (In the event something does go wrong with your install.) - For me a 3amp fuse in the board has been more than enough for all my installs. The 10amp fuse has been overkill.
