Lithophane Picture Frame Set

TLDR: A fresh take on traditional lithopane prints replaces light boxes with a striking contrast effect achieved by spraying black paint on the back of the print. Use http://3dp.rocks/lithophane/ to generate 3D models, adjusting image and model settings as shown in provided screenshots. Download background and frame files designed for 200mm square images with a 5mm border, resulting in a finished frame just under 12 inches square. I started experimenting with lithophane pictures last July, initially planning to create a light box or similar display. However, I encountered issues printing thick enough to prevent the image from appearing washed out. To resolve this, I discovered that printing thin images can be offset by placing them over paper, allowing for greater control and reduced image washing. Recently, while sizing background pieces for printed pictures, I noticed how a darker background significantly enhances contrast. My next thought was to purchase construction paper and consider gluing it behind the print to increase contrast. However, it soon hit me - spray paint the back of the print with any color desired. After one trip to the hardware store, my project was complete. The frame is centered around a 200mm square lithophane with a 5mm border generated from http://3dp.rocks/lithophane/. The background opening accommodates a 195mm picture, while the boarder ensures the picture remains attached to the background piece. The wood frame part can be made from various materials and is designed to interlock with another print when four are printed together.
