Ultimaker Heated Aluminum Bed

I used my CNC machine to mill an aluminum plate to fit using the stock Ultimaker bed bolts and springs.

This is the file I used to create the G-Code for milling. And some brief instructions how to get it working.

I selected 0.25" mill finished stock from 80/20 surplus on ebay. I got enough material to make 2 beds so I can swap them in and out.
