I'm Blake, parent of Eno and Bean, six-year-old twin boys who love building things. Like a lot of kids their age, they're obsessed with Minecraft. They're also obsessed with our 3D printer. They wanted to design their own prints, but every tool we tried was too complex for their age level.
Voxelkid started as a 3D design solution for my own kids. We wanted to take the block-stacking mechanic they knew from Minecraft to make real, printable 3D files. No CAD software learning curve. Just build something, hit export, and have it in their hands as soon as the printer works its magic.
Kids build in a 3D grid using blocks in three sizes — 4 mm, 8 mm, and 16 mm — within a 232 mm × 232 mm × 232 mm build space that fits on any home printer. They can paint with eight colors, orbit the camera to check their work from any angle, and undo anything that goes wrong. Kids can save their work as .json files as they build.
When their 3D build is done, one button exports a print-ready STL or 3MF file ready to drag into your slicer and print.
Old enough to build independently, young enough to need simple tools.
No installation. Works on Chromebooks and school devices.
Compatible with Bambu, Creality, Prusa, and every other slicer.
Building, saving, and sharing are free. Export to print when you're ready.
Screen time with a physical payoff is different from screen time without one. When a child designs something and then holds it in their hands — something that didn't exist an hour ago — that's a different kind of experience. That's part of what Voxelkid is for, helping kids feel empowered rather than absorbed by technology.
Voxelkid runs in any browser — no download, no sign-up. Just open and start building.
Questions, feedback, or just want to share what your kid built? We'd love to hear from you.
