Any size
From a 1×1 button to a 12×12 slab. Tall bricks, thin bricks, smooth caps — in giant jumbo or classic standard size.
Design a brick right here in your browser, put studs wherever you like, and download a print-ready STL. They snap onto standard jumbo bricks — no glue, just that satisfying click.
What you can make
One little tool, a whole bin of possibilities. Configure it, spin it, print it.
From a 1×1 button to a 12×12 slab. Tall bricks, thin bricks, smooth caps — in giant jumbo or classic standard size.
Tap studs on or off, one cell at a time. Spell a letter, leave a window, build a ramp.
Sized from real jumbo bricks — ⌀35 mm studs on a 47 mm grid. Print it, let it cool, click it on.
It's your filament. Bubblegum, cobalt, glow-in-the-dark — the STL doesn't care, so go wild.
How it works
No CAD, no accounts, no uploads. It all happens in your browser.
Pick a size and tap the studs you want. The 3D brick updates live as you go.
Spin it, flip it, peek underneath. What you see on screen is exactly what exports.
Download the STL, slice it, print it. Then snap your new brick onto the pile.
Any colour
Same design, every filament you own. Mix a set the shop never sold.
Bricks come out in whatever colour you feed the printer.
For makers
Thin-walled and hollow-studded to save plastic and time, and shaped to print without a support forest.
Free. No sign-up. It runs entirely in your browser.
Start building → Design → preview in 3D → download STL. About thirty seconds to your first part.
