Name Puzzle turns any name into a chunky tray puzzle: every letter is its own piece, and the space around the letters auto-fills with Tetris-style pieces, colored so no two neighbors match. Letter Height sets the puzzle's overall size — go big for toddler hands. Piece Clearance is the fit between pieces: around 0.2mm gives a satisfying snug fit, a little more if your printer squishes first layers. Choose print-in-place to print the whole solved puzzle at once, or separate parts to run each piece in its own color. Pieces print flat with no supports. PLA is ideal; for small children, size the pieces up, give edges a quick sand, and prefer the chunky settings over fine detail.
