Lithophane window frame

A simple frame for hanging lithophanes in a window using a suction cup. Sized for a 204mm width x 216mm height lithophane. If you need another size drop a comment and I'd be happy to adjust the design for you. Can also adjust the suction cup hole size if you can't find one to fit. Support removal can be a little tricky-- I run a razor blade along the top and bottom edges of the supports around all sides then pull with a pair of pliers.
