These are size 4 (~5mm) gauges with a snap fit connection and the corresponding snap fit piece. Right now, there is only a sphere, but I plan on making more in the future. All you should have to do it push the sphere piece into the hole of the gauge, and it will snap together. You won't need supports on the gauge piece but I would recommend them on the snap piece. I made these with the idea of being able to print a variety of colors and shapes to make your gauges more customizable.

If you'd like a different size gauge or a different design snap piece, let me know, and I'll see what I can do.

If you make this please share your make, I'd love to see it!
