PrintABlok are interlocking building toys created by the 3D Printing Professor, designed to work well on home 3D Printers. PrintABloks can be built in all 6 directions, allowing for gravity defying building unlike any other building block out there. PrintABlok.com

Use the included .blend file to create custom sized bloks for your projects.

BASIC SKILLS

Turn a connector piece so it will fit into the hole in a blok, and press it in with another blok until they click together. It should hold fast until you give it a little pull to separate them. You may occasionally need tools (like needle nosed pliers) to pull the connectors out of the bloks.

ACCESSORIES

You can make accessories for your PrintABloks using the included negative shapes to cut cavities out of the holes of objects. However, if you'd like a high-quality library of accessories parts compatible with PrintABloks, including articulating bloks, mosaic bloks, and mech parts, go to PrintABlok.com.

REVISED VERSION NOTES

12 March 2020 a new version of the connector negative and a revised base block was updated. This new connector hole includes several small changes to increase printability on all machines and making use easier. There were no changes to the connector so backwards compatibility was maintained. November 2025 Added Blender soruce files to make it easier to make your own.

25 August 2021 A re-revised connector negative and re-revised base block was again updated. This, again, increased printability while maintaining backwards compatibility. Legacy files were zipped up and included for historical reasons, but it is highly suggested you just ignore those.
