Interlocking block toys with the exact same H-shape lock as our full-size landscaping blocks — just pocket sized, 3D printed in tough, plant-based PLA+ plastic. Stack them, lock them, and build walls, forts, castles, and anything else you can dream up. No glue, no studs required.
Shop Sets & Packs How They WorkEvery toy block is a miniature of the real thing: a raised H-shape key on top and a matching channel underneath. Courses lock together exactly like our full-size blocks do on a job site — which means what kids build actually holds together.
An original Something LLC design, scaled straight down from our real landscaping block — no rebrands, no knockoffs.
Each block is 3D printed in PLA+ — a firm, plant-based, BPA-free plastic — then inspected and finished by hand in our Alabama shop.
The H-shape interlock self-aligns every row. Builds stay standing through real play — and pull apart clean when it's time to rebuild.
Pick your sets, choose your colors, and check out securely with PayPal or any major credit or debit card. Every order is 3D printed just for you in our Alabama shop and at your door within 2 weeks. Flat $8 US shipping ($25 international). Recommended for ages 4 and up.
Everything you need to start building: 24 H blocks (1-inch cubes), 4 Corner blocks, 2 Tri blocks, and 2 big Quad blocks (2 inches). Enough for a full four-walled fort.
Running low on one block type? Top up with a single-type pack.
The workhorse of every build — 20 more 1-inch H blocks to run your walls longer and higher.
10 Corner blocks for clean turns and L-shaped builds.
10 Tri blocks — a corner with a built-in straightaway, so you can branch interior or exterior walls off any straight run.
10 Quad blocks — the big 2-inch hub that intersects four walls into one piece.

H blocks are 1-inch (2.5 cm) cubes. Corner-family pieces get bigger from there, up to the Quad at 2 inches (5 cm). The 32-piece Starter Set builds a full four-walled fort.
Yes — every Something LLC set and refill pack is the same scale with the same H-shape interlock, so your collection always grows. They are not compatible with LEGO or other stud-based bricks.
When you add a set to the cart, you choose a color for each block type in it. Every block of that type prints in the color you picked. Want a mix? Add the same pack to your cart more than once in different colors.
Hand-wash in cool, soapy water and air dry. No dishwashers — and don’t leave blocks in a hot car or direct summer sun, since PLA softens around 130°F.
Every order is printed fresh in your colors and at your door within 2 weeks (US orders), with tracking sent to your email. Full details in our store policies.
