Stained Glass Peacock

[Commercial license access is now provided for this model at Thangs dot com/designer/tlavedas1]

***Note*** This model has been updated (as of Sept 2025) to provide the correct version of the STL file of the second (rear) piece as a mirror image so that the flat sides can be mated together.

This is a two-part HueForge Lithophane of a Peacock in a stained-glass style, as suggested by a follower. The first part has the white, greens and blues of the foreground with the reds blanked out. The second part blanks out parts of the bird and provides the reds and yellows for the background. In the second part the green parts are maintained and some are made lighter to permit some yellow to occupy those areas.  These areas blend with blues when the two parts are mated to make green in the completed model.  The image halves are tailored to yield green leaves.  Though there is green filament included in the 3MF file, it is actually optional.  Two layers are suggested in the front part to blend with the blue for some turquoise effects, but they can be omitted or blue substituted for a bluer result.

Feel free to substitute your filaments, but seek to use ones with similar transmission distance (TD) values.  The base layer should be the most transparent white filament you have (TD > 10, suggested), like a natural or transparent.  The design assumes PETG for thermal resistance, but PLAs can be used, if the risk of exposure to very strong sunlight is low.

***IMPORTANT NOTE*** Both parts have very thin base layers, so special care is needed to remove them from the print bed. It is probably best to cool them completely before trying.  A few minutes in a freezer and/or some glue stick as a release agent is wise.

When joining the two parts be sparing with the adhesive, especially in the lighter parts. The adhesive will change the colors if it is not behind the darker parts. I just used some around the dark parts and around the very edge to keep the glue from showing. If spread thin and uniformly, it should not show too much.
