A rechargeable battery and speaker attachment for the original Organelle. So now all of us that own the older version can also join in on the portable fun.
👀 Since the photo and video was taken, I've swapped the straight DC plug for a right angled DC plug.
Here's a brief video showing the guts of the backpack and the portable goodness.
- Width
266.8 mm(10-1/2 inches) - Depth
87 mm(3-7/16 inches) - Height
28.5 mm(1-1/8 inches)
The base is designed to be 3D printed and only adds an overall 19mm (3/4 inches) to the height of the Organelle. If you don't have access to a 3D printer (public maker space, library, work, friend) you can used a 3rd party service via Tinkercad, Thingiverse, or wherever you choose. Below are links to various 3D file formats, I used the STL file to print mine on a Markforged Mark Two printer.
| Format | File |
|---|---|
| GLTF | organelle-backpack.glb |
| MTL | organelle-backpack.mtl |
| OBJ | organelle-backpack.obj |
| STL | organelle-backpack.stl |
| Tinkercad | Organelle Backpack |
These are the parts you'll need in addition to the 3D printed backpack. I sourced parts from 3 different vendors; Mouser, Pololu, and Amazon, you might be able to source everything through a different vendor.
ℹ️ The USB A breakout is optional, as you can see above I simply spliced an old USB cable I had lying around.

Below is a simplified wiring guide; 🔴 is positive voltage ⚫ is negative voltage/ground. You'll need some decent silicon wire (22–28 AWG) to ensure a quality build as well as a soldering iron.
