I had built another one of these and am very pleased with it, so I made another with a smaller foot print and 2 negative posts.
To save the space, the cables are moved from the front of the power supply to the rear and tucked in to a pocket beneath the handle. You’ll need to either drill a hole in the top cover of the power supply to re-route the wires or remove it completely. If you leave the top cover off, it will need to be glued together otherwise it should stay together with pressure.
The handle connects to the center piece with a dove tail.

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!
