We have a limited number of Crow's Nest products available
This is a set of two plexiglass discs designed to be used in a base for the Proteus. The discs are approximately 11 inches in diameter. The top disk laser cut 1/16 inch plexiglass and silk screened w/large hexes and zero module. The second disk is laser cut and laser etched with small hexes. The were designed so you can build a lighted base for your Proteus. The discs are covered with a protective film that you will need to peel off.
To the best of my knowledge, the Proteus base was never offered for sale.
