I needed a neopixel holder for a Halloween costume of mine, so made this. it has holes on the bottom to get to the pins on the neopixel, as well as one on the side to lead them out, which ever is preferential. There is quite a bit of tolerance, height and internal, to fit wires and hot glue :)
Edit: Sorry guys i realized its upside down, please flip for easy printing. Im pretty new at this so unsure how to flip it in the software.
i printed at 100 infill, but im sure 20 would work.
