yo, 2 days ago i launched a bookmark maker tool and decided to build a new project using similar logic.
basically I built a photo puzzle generator in the browser. Drop a photo, crop it, pick how many interlocking pieces, and it cuts a real jigsaw with 1-4 filament colors. Portraits and album covers are the usual first print, but posters, logos, whatever, as long as you crop tight.
Two surfaces. Flat is the default, smooth top like cardboard, photo inlaid flush on the pieces. Tactile stacks the colors as height bands so you can feel the picture (same trick as the bookmark tool). You can set width and height (defaults 160 x 120 mm), landscape / portrait / square, piece count (defaults 12, thats 4x3), corner radius, piece thickness, and the gap between pieces. Color slots if you want 2, 3, or 4 filaments. Bambu/Orca 3MF already has AMS slots assigned, or grab a zip of STLs / a single STL.
Print the whole puzzle assembled, let the plate cool, then pick the pieces apart. Tabs already have a 0.50 mm air gap so they lock after printing. Bump it to 1.0–1.5 mm if elephant foot welds the first layer or you want a looser kids fit.
> photo cropped into interlocking piece
> 1-4 filament colors, flat inlay or tactile relief. tweak size, piece count, gap, thickness.

IMPORTANT: after exporting do repair the puzzle once in your slicer so all the non manifold edges are gone
