3D Printed Building Blocks

Get Started With Bricklets

Bricklets are 3D printed components built to interface with each other. We provide an open source database for a variety of bricks. Our goal is to provide a system of reusable electronic building blocks that can help you build exciting programmable mechanical gadgets.

Reference

This concept was developed to teach the fundamentals of rapid prototyping and electronics. Learn about rapid prototyping with bricklet and how you can design your own building blocks. We encourage people to make their own parts to understand just how things work underneath the surface. We hope that this system will inspire you to build amazing new things.

Basic Dimensions

The Vertical Pitch, or height of a classic brick (ignoring the peg) is 9.6 mm

The Horizontal Pitch, or distance between knobs is 8 mm

The Horizontal Tolerance is 0.1 mm

This is half the gap between bricks in the horizontal plane.

The Knob Diameter is 4.8 mm

There is a tolerance of 0.05 mm for holes and axles

The Knob Height is 1.8 mm


The Unit Block

The basic 1x1 unit block is 11.4 mm tall and 8 mm wide

The rectangular portion is 9.6 mm tall while the peg is 1.8 mm tall

From the top view, the knob diameter is 4.8 mm

From the bottom view, the internal hole is 4.8 mm x 4.8 mm

It must recede at least 1.8 mm into the brick
