About this 3D model
Customized version of http://www.thingiverse.com/thing:83812 Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=83812 This is the first thing I thought of when I saw brainbounce's lithopane gallery customizer. Made one with the top 2 rows and another with the bottom row. Should be able to glue the bottom row on to get the complete display!
