I completed the front panel today. 

1. Laser cut 3mm white acrylic for the front and back layers of the panel
2. Attached the panels together (IPS Weld-On 3 Acrylic Plastic Cement)
3. Spray Painted them with a Matt Dark Green from  Rust-o-lium
4. Taped down and cut a piece of cardstock for alignment, and burned away the paint leaving the white behind
5. I then mounted everything.

Up next:

• Test/code the indicator lamps below the knobs
• Design and 3D print a frame to hold the lamps, marble and UVLEDs
• Cut the base piece which holds the power supplies and Geiger counter
