These are 125 mm metric optical breadboard tiles, which can be interlocked on the bottom side using connectors. This was specifically designed to hold M6 DIN934 stainless steel nuts of 5 mm thickness inside, so that the breadboard thread is sturdy and robust. Pause the print at the right layer height (the Cura settings are given in one of the pictures), insert the nuts, and proceed to lock the nuts inside. The design was specifically made to print with 0.2 mm layer height and 4 wall layers. I added a test cube so that you can assess whether the nut insertion proceeds to your satisfaction. The interlocking works quite well, but you may have to shave off a little bit of material to improve the fit. You also may need to add some support underneath to prevent larger assemblies from sagging, as of course this will not be as sturdy as a steel or aluminium breadboard. However, it is a much more cheap (~2€ per tile) and accessible alternative!
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
