There is space inside the hollow gem to take two led’s in series I chose to salvage a couple of white ones from a cheap torch/flashlight.
All of the parts should fit together as shown in the pictures.
The part labelled switch stopper is optional and simply prevents the switch pushing back inside the ring body when the button is pressed.
The battery contacts are simply made from the legs of a capacitor quite thick, 0.8mm 0.03in and should be bent to fit, with a slight hump where the contact with the battery is made, I think the pictures show this.
The wires can be super glued in place as should the non contact parts of the battery contacts.
I found the best orientation for the batteries was positive down and is wired accordingly.
Ignore the orientation of the batteries in the picture with the ring showing IKEA on the top, they should be IKEA side down.
I used a switch salvaged from an old monitor control panel, you may have to find something similar, The printed power button simply glues onto the switch when it is place.
The printed layer immediately above the switch may not print at all, it’s very thin, but is not important.
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.
