This is a sandwich case for the Iris rev4 keyboard from keeb.io.

The top plate is rigid by being thick and solid, no noticeable bend or give, even compared to metal plates once installed. Each switch hole has a lip to clip onto, rather than being pressed in.

The middle layer is from the official case design repo: [https://github.com/keebio/iris-case](https://github.com/keebio/iris-case) In the photos I've used "clear" PLA to get the shine-through from the builtin underglow LEDs.

The bottom has a honeycomb effect from the infill being honeycomb patterned with the LEDs shining through.

I've included the original Fusion 360 design file if you'd like to explore it or make modifications. Enjoy!

100% for the top plates for rigidity, 10-15% for the bottom.

The top plates should be printed upside down, negating the need for supports.
