3D print a 3" cube with 1/8" thick walls.
Mill your wood base. I made the pocket that the glowing shade sits in 1/8" deep. I used a speed of 22 and a depth per pass of 0.04" on the Shapeoko 2.
Cut 1/4" thick cork into small circles. Glue them onto the bottom corners of the wood base.
Can you post your STL file for the 3D print?

Hey Jeff, the file has been posted!

Thanks Bryan! You may want to check out the Omaha Maker Group. There's also a makerspace (with a 3D printer) at the Omaha Children's Museum; that could be good depending on the age of your school kiddos :)

Wow Robert, that material looks really cool. Thanks for the recommendation. I will definitely check it out.
