This is BERT, a Buildable Educational RoboT.

BERT is very affordable because it is open source and uses off the shelf parts. BERT is wifi enabled and only needs a browser to control and program. BERT is a fun and engaging tool to learn engineering, coding, and 3d modeling.

These stl files are designed for better build plate adhesion. No supports are needed. A nozzle size of 0.4mm or less is recommended due to the print details. For the best Lego compatibility, we recommend printing parts in PETG.

The source code to drive BERT is available at

We hope you enjoy using BERT. Please tag your modifications with "busylabs" and help spread the word about BERT.

About us

All our 3D models contain a ZIP archive with STL files and previews.

Our collections of 3D models created by a community of 3D enthusiasts. These models are suitable for both 3D printing and CNC

With our help, you can already search for models on all popular sites on the Internet. We have various filters for a quick search. Our developers are constantly working on a user-friendly user interface. All so that you can find a 3D model to print or CNC and put it to work faster!

We really hope that you can find the 3D model you need for your work or hobby.
