Lithophane Maker
Lithophanes and chromaphanes, paired with the LithophaneMaker software. Dormant.
All lithophanes: the channel demonstrates the creator’s LithophaneMaker.com software (photos to lithophane STLs, including a desktop app), with builds like five-sided lithophane light boxes and moon-lamp spheres, plus “chromaphane” filament-painting tutorials. The couple also runs American Filament for lithophane-grade filament. The channel hasn’t uploaded in about a year, so treat it as a how-to archive for the niche.
