Here is a quick video that captures our motivations for doing this project:

In this Instructable, I will try to share the process of making these one-of-a-kind speakers.
*Note: for this project, we used an off-the-shelf speaker driver. The exact speaker can be found here:
Step 1: Creating the Model
1. Flexible rubber base (Objet TangoBlackPlus)
2. Clear crystal-like protrusions (Objet VeroClear)
The clear crystals are held in place by the black rubber base, which gives the lights that cool pixelated effect.
To create the crystal form, I used Autodesk 3ds Max Design 2013, and its powerful Topology toolbox. The steps in 3ds Max are as follows:
1. Create a polygonal sphere from the standard primitives box. Use a sufficient number of segments, but not too many
2. Convert the sphere to an editable polygon with the Edit Poly modifier
3. Ensure that you have edges selected in the Edit Poly Mode box on the right hand side
4. In the Polygon Modeling drop-down of the Graphite Modeling Tools, select "Generate Topology"
5. In the pop-out menu, select "Edge Direction" (or whicheverpattern you happen to like!)
6. In the Edit Poly Mode box, select polygons. Right click in the workspace and select the box next to "Extrude"
7. In the pop-out menu, change the extrude mode to "By Polygon"
8. Extrude all of the faces a sufficient distance.
9. Export your creation as a .STL (StereoLitho) file
Step 2: Finishing the Model
To convert the .STL mesh into a solid body in Inventor, you'll need to install the free Autodesk Labs plug in: Mesh Enabler, which can be found here:
To complete the model in Inventor, follow these steps:
1. Import the .STL file you created by selecting "Open" and changing the file type to ".STL"
2. Right click on your model name in the model tree on the left and select "Convert to Base Feature"
3. Change the selection to "Solid/Surface" and click OK
4. Create a hollow sphere for the base using the Revolve tool. (Make sure to create a new solid body in the tool options)
5. Use the Combine tool to create holes in the base where the crystals pass through
6. Perform a Revolve cut on the outer surface to smooth out the sphere
7. Using the standard Inventor modeling tools, add all the features you need to mount the speakers and allow the wires to pass through
8.Export each body as an .STL file individually by hiding the other bodies. This will allow you to apply different materials to each body
Step 3: 3D Print the Speaker Enclosure
Once they are printed, you have to clean them up with a pressure washer and wet sand them to the desired finish.
