Circuit Playground Express Case with NeoPixel holes

thingiverse

I'm planning to mount a Circuit Playground on my stairwell wall as a nightlight. The case Adafruit created is fantastic (love the smiley face!), but I required a hole in the base so that I could attach it with a nail, and holes in the lid so that the NeoPixels can shine brightly. This is my very first 3D design, and while the print turned out reasonably well, I think it still needs some improvement. I'm concerned that the lid might be a bit too thin. However, with some paint and a small amount of sticky-tack, it works great as a beginner's effort.
