Open Manufacturing: A Home for the Beagle Bone #3dthursday

3DPrintedCase_BeagleBone

Check out this helpful post about how a team planned for Open Manufacturing for a project involving a BeagleBone. From IHeartRobotics:

The first thing is to frame what you want to build by constructing a list of constraints and intentions for guidance. In our case, we decided it needed to consider following:

  • Access to all of the ports with special consideration given to SD Card removal.
  • Maintaining minimal dimensions
  • Able to be mounted to the TurtleBot using a universal set of mounting holes.
  • 3D Printable Design

Doing this creates the “world” that your design lives in and as such the tools you may consider using and the initial ideas for construction.

The next step is to obtain or create a 3D Cad replica of the Beagle Bone board. If one has to create their own model for testing, it’s best to note that only the major dimensions of the board and components necessary to the case are needed, but they must be accurate.  These include the board itself, it’s ports, mounting holes, and anything that one may feel needs to be built around to complete the case. 

Now that we have a physical and 3D model of the Beagle Bone, we can start to draw out the general outline and order of feature construction. I personally rough out a general model idea on paper and then begin creating in a CAD program of choice with the frame. Testing and experimentation are important parts of the design process. I constructed a rough case frame that wraps around the Beagle Bone and printed the piece to test the tolerances and fit. Doing this is beneficial to designers as it saves time over the long term versus running into an unaccounted error later in the process. The idea uses empirical analysis to verify quantitative and qualitative data….

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!


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
