ShapeStack – Customizable Stacking Learning Blocks

🧱 ShapeStack is a set of chunky, stackable learning blocks that interlock into wobbly towers — and teach while kids play. Each block is a rounded shape with a character raised on top that nests into the engraved base of the next block, so the whole stack clicks together as it grows. Stack them in order, sort them by shape, or build silly mixed-up towers. Comes ready to print in three sets, with more you can invent yourself: 🔢 Numbers (0–10) — each numeral on a different shape, and each block also carries a dice-style dot count on its side faces, so children connect the symbol to the quantity as they count and stack. 🐶 Animals (Dog · Cat · Mouse · Cheese) — a playful little stack with friendly raised faces and the animal's name engraved on the side. ⬟ Shapes (square, triangle, pentagon, hexagon, circle, star) — each block shows its own geometric symbol for early shape recognition. 🎨 Make it your own — everything is customizable ShapeStack is fully parametric in OpenSCAD (and on MakerWorld's Parametric Model Maker). You can change: Shape — 14 options: triangle, square, pentagon, hexagon, heptagon, octagon, nonagon, decagon, circle, star, plus four card suits (spade, club, heart, diamond) Size — width 40–150 mm and height 10–20 mm Top character — raised, and it's what interlocks with the block above Bottom character — engraved, receives the block below Two lines of side text — one word on the alternating faces, a second word/symbol on the faces in between (letters, numbers, dots, or emoji) Colour — per block Three independent fonts — mix text and emoji on different faces of the same block Edge rounding, bevel size, engraving depth, and stacking tolerance — tune the fit and feel That means you can print any letters, numbers, words, names, or symbols — spell a child's name, build the alphabet, make a counting set in your own colours, or a deck-of-cards stack. 📦 What's included 6 ready-to-print profiles (.3mf) — Numbers, Animals and Shapes, each in a multi-colour (AM
