This stained-glass styled Hummingbird print is in TWO parts developed with HueForge's Lithophane Blending Type. The first part has just the blues and black of the Hummingbird foreground. The second part blanks out the foreground and blue parts of the hummingbird and provides the reds and yellows for the bird.

I printed this model in PLA, initially, but switched to PETG to make it more resistant to warping in strong sunlight. But PLA can be used, if the model is kept out of strong sunlight. Both parts have very thin base layers, so special care is needed to remove them from the build plate. It is probably best to cool them completely before trying and maybe to use glue stick as a releasing agent.

The two parts are printed as mirror images so that the flat sides can be mated together when assembling the model. When joining the parts be sparing with the adhesive, especially in the lighter parts. The adhesive will change the colors if it is not behind the darkest parts. If spread very thin and uniformly, it should not show too much.

If substituting filaments, pick ones with the similar TD values (+/-1). Use a transparent or natural white, if possible. Otherwise, pick the one with a TD > 15 to minimize the color change it will cause.

The 3mf file was created using Bambu Studio which has the swaps defined already. If necessary the STL files can be used in other slicers with the swap information provided below.
