One Euro Tokens with Hidden Internal Lithophanes

thingiverse

These are One Euro shopping cart tokens featuring a hidden lithophane inside, which can only be seen when viewed against a bright background light. I also created Loonie tokens that can be found on the Thingiverse platform. The models included come with different pictures for the lithophane, as well as a solid token without any lithophane. The OpenSCAD file used to generate these tokens is available, allowing users to create their own designs or adapt the model for use in other countries. To achieve the best effect, the picture should be in greyscale with high contrast and include some pixels that are completely black to enable direct printing on top of certain areas. The lithophane measures only 1.88 mm in height and 21.03 mm in diameter, so it's essential not to expect a lot of detail. Tokens featuring lithophanes must be printed at 100% infill for the lithophane to print correctly, and users will need to use light-colored filament to allow the light to pass through.
