• Off‑the‑shelf breadboards are limited, lacking support for wide development boards. • Ludwin’s 3D printable breadboard adds a large hole, enabling ESP32 and other wide boards. • Only the plastic shell is printed; metal contacts are inserted from commercial boards or purchased separately. • GitHub repository hosts designs for ESP32, Raspberry Pi Pico, and Arduino Nano, plus other variations. • Variations include a single large space and other layouts for versatile component accommodation. • Community discusses repurposing wasted space as voltage rail or cutting breadboards in half.
Article Summaries:
- Although off-the-shelf breadboards are plentiful and cheap, they almost always seem to use the same basic design. Although you can clumsily reassemble most of them by removing the voltage rail section and merging a few boards together, wouldn’t it be nice if you had a breadboard that you could stick e.g. one of those wide ESP32 development boards onto and still have plenty of holes to poke wires and component leads into? Cue [Ludwin]’s 3D printable breadboard design that adds a big hole where otherwise wasted contact holes would be. The related Instructables article provides a visual overview
