Organize projects with these modular Lego base plates for STEMMA boards! These 3d printed holders feature built-in standoffs for press fitting the PCBs. 

It’s a nice way to secure them without screws or adhesives.

STEMMA board and sensors allow you to plug-and-play together various devices and accessories, without any soldering!

In this project, we'll build Lego base plates for all of our STEMMA boards! We designed several different sizes to to fit all of our boards!

On the bottom are tubes that are designed to fit onto LEGO compatible bricks.

The clearance in between the PCB and holder allow space for components on the bottom of the PCB.

We also designed lego plates for a couple of components like Feather boards, battery pockets and a slide switch.

All of the base plates print will out any supports and the built-in pegs allow board to simply snap to place without any additional hardware.

Slicing Parts

Slice with setting for PLA material. The parts were sliced using CURA using the slice settings below.

  • PLA filament 215c extruder
  • 0.2 layer height
  • 10% gyroid infill
  • 60mm/s print speed
  • 60c heated bed

Glue 

We use super glue to adhere the brick studs / tubes. Apply small even dots on one of the part, align both parts and gently press together. Allow the parts to dry for at least 10 minutes before use.

Follow the directions on the super glue container, do not touch with fingers, please wear eye protection and be careful. Older makers should help younger ones.
