This print is for holding addressable LED's used in this project: https://slingtsi.rueker.com/making-a-led-powered-metar-map-for-your-wall/
Using clear filament, for penetrating the foam board and using this model to hold the LED, the color of the LED will show through the foam board as a little light, rather than a big LED. The 3D printed LED holder is hot glued to the back of the foam board after centering on the filament.
I used clear filament to print, but not required. No supports are required. I printed 50 at the same time.
