We build the electronics. You print the rest.

Solderless electronics kits for 3D printing

Start with a real, working FM radio: an assembled board, plug-in parts, your printer and an afternoon.

The Tall Boy, a 3D printed tabletop radio built with the FM Radio Kit

Electronics you can design around

Printing a great looking case is the fun part. Getting working electronics inside it shouldn't be the hard part.

No soldering

The board arrives fully assembled, and every part connects with a JST plug. If you can plug in a phone charger, you can wire up a kit.

Made to fit your design

Board dimensions, mounting holes, connector positions and a STEP model are all published, so you can model an enclosure around the electronics with confidence.

Open documentation

Schematics, bills of materials, CAD files and build guides are free on our docs site. Use our designs directly or take them apart for ideas.

How a kit comes together

  1. Pick a kit

    Start with the electronics for the thing you want to make.

  2. Print an enclosure

    Print one of our project designs, or model your own around the published dimensions.

  3. Plug it together

    Connect the parts, fit them in your case, add batteries and switch it on. No iron required.

The Tall Boy radio

Start with the FM Radio Kit

Our first kit is a battery powered FM radio with built in volume and tuning controls. Plug in the speaker, antenna, power switch, LED and battery holder, then fit it all into a case you printed.

Who it's for

Makers who design their own models

Treat a kit like a part in your CAD library. Model a retro cabinet, a portable radio or something nobody has thought of yet, and drop the electronics in.

Board dimensions and CAD

Sellers who print in batches

Selling at craft fairs or Christmas markets? Order kits in quantity and turn your prints into finished products people can take home and switch on.

Bulk orders

Classrooms and first time builders

A complete radio with no soldering makes a friendly first electronics project for students, STEM programs and anyone curious about how things work.
