I have found a good source for quality clear plastic display cases that fit my Ethereal Maze Puzzles very nicely. The medium size case is about $3 and is perfect for "Escher’s Playground". The large size case is about $5 and is for "Twisted Symmetry" or "Minotaur’s Castle". The medium size case is shown with the maze with the red ball, and the painted maze is in the large case.
I put some links for purchasing these display cases on the main page of my Ethereal Maze Puzzles Shapeways Shop:http://www.shapeways.com/shops/EtherealMazePuzzles
You can use them to get one of the cases with Free Shipping. So if you have already purchased one of my mazes, and want to display it as a work of art, this is a nice display case to have.
The medium size case is about 2 inches wide, and the large case is over 3 inches wide.
