Parametric Building Block

A playful, fully customizable construction brick! 🎮 Balls (studs) snap into round sockets, so the pieces lock together and you can keep building. The best part: you design your own brick. ✨ Just type a simple text grid in the Customizer ⚠️⚠️⚠️ no CAD skills needed ⚠️⚠️⚠️. A few layouts come ready to use as a starting point, but the whole idea is to make it yours: strips, squares, crosses, L-shapes, frames... let your imagination run! 🚀 🛠️ Make your own brick Each piece is a grid of square cells. In every cell you choose what goes there: a ball ⚪, a socket (hole) ⭕, plain flat plate ⬜, or nothing at all to carve out the outline. Mix them however you like and the brick takes shape instantly. ⚙️ Customizer — only two things to set 🧱 Layout — a little text grid that describes your brick: SymbolMeaning0⬜ flat plate (no feature)1⚪ ball (stud that sticks out)2⭕ socket (hole that receives a ball)x✂️ no plate (empty cell — shapes the outline) , separates columns (left–right) ↔️ ; separates rows (front–back) ↕️ Shorter rows are centered automatically 🎯 🎚️ Tolerance (the fit): this is the magic knob for a good snap. It sets how much the ball is oversized compared to its socket, in millimeters. A bigger value = tighter, firmer click 💪; a smaller value = looser, easier to pull apart. Every printer is a little different, so if your first pieces are too loose or too stiff, just nudge this number. 👉 The fastest way to dial it in is to print one ball and one socket and test the click before making big pieces. 🌟 Example 🌟 The grid 1;2,1,2;1 builds a cross ➕: 1,0,2 — short strip: one ball, one flat, one socket 1,1;2,2 — 2×2: two balls in front, two sockets behind x,1,x;2,1,2;x,1,x — the same cross, written out in full 1,0,1;0,0,0;1,0,1 — square plate with balls in the corners
