Marble Track Base

I designed this to fit on the bottom of the 3D Printed Marble Machine #3 - Designed by Tulio Laanen

I wanted something simple that I could put a roll of LEDs into. The marble run sets inside of it with a clearance fit. I printed the marble run in clear PLA and lit it with the LEDs in this base.
