Create your own double slit experiment! From kseluga on Thingiverse:
All the parts were designed with FreeCAD. The stand was designed to hold a 14 mm diameter laser pointer. If you have one that is a different size, you can make two easy adjustments to make it work with your pointer. First, go FreeCAD and open the original CAD file. Next, change the radius of the horizontal stand cutout (cylinder005) to be slightly larger than the radius of your pointer. Next, enlarge both cylinders of the button clip to fit your pointer (Cylinder_Outer and Cylinder_Inner). A tight fit is not necessary. The pointer just needs to rest easily in the stand so it doesn’t move while you observe your results.
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! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. 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!
