Ender 3 LED Light Bars

A Light bar system that fits 10mm-wide LED strips. Designed for an Ender 3, but should work for any printer with similar Y channel extruded aluminum rails. The arms are designed to be strong but flexible.

You can go with an out-of-the-box LED set like this one from Amazon, or build your own custom smart MOSFET color-controlled thing. I'd love to see what you come up with. If you buy this LED strip from Amazon, you'll be cutting quite a bit of it off...
