I wanted spotlights for my 3D printer cabinet so I decided to draw stage-like spotlights in miniature. I use LED’s from Hobbyking and run them on roughly 130mA without overheating. https://hobbyking.com/en_us/super-bright-3watt-white-led-lamp-with-aluminium-heatsink.html
It is designed to be printed with the parts oriented as in the picture. I used Cura for slicing, and 0,2mm layer height turned out better than 0,1mm on my Prusa mk2 at 60mm printing speed, black PLA.
Note that the front and rear piece are purposely not press-fit as printers have different precision and it’s easer to add a bit of for example melt glue to make them fit tight.
The cables are fed through the hole in the back, you need to use a knife to remove some material from the edges where the LED rests in order to keep the LED level.
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!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
