Stained Glass Style Lithophane Bluebells

This is a two-part HueForge Lithophane of some Bluebells and other flowers.  Unlike my previous stained-glass efforts, this is the first using HueForge Color Match Mode to separate the colors of the two parts.  That is, a minimal amount of preprocessing of the image in an editor was done.  Specifically, the editor was used to remove the background outside of the central circle and to add a loop for mounting.  This approach can simplify the workflow some while requiring some compromises in getting the colors separated.

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.

 NOTE:  If using STL files, the second part must be Mirrored around X-axis in slicer for the flat sides to be mated when assembling.

***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.
