In an essence, the project is about building a new customized shell for a commercial bluetooth earbud components.
Think of it as building musicians custom in-ear monitor, but wireless. The product of interest is Sennheiser Momentum TrueWireless 2 (MTW2).
The reason for the project is:
I bought a bluetooth earbud, but it doesn't fit my ear. It might seem simple, but bluetooth earbud is there to make listening simpler. But if it brings another problem, what use does it have? I thought of purchasing another product that will fit my ear, but I could use this chance to practice on skills that I've learned and possibly learn new skills. As a side note, a part the motivation came from using UM20 by Westone.
The main outcome of the project will be:
3d printed parts
Exposure to 3D scanning of objects and working with mesh - or reverse engineering as whole
Surface modeling
Software - Rhinoceros
DFM materil properties of 3D printing parts
I assume the shape of MTW2 (right) is motivated by the in-ear monitors. UM20 by Westone (left) is not fully custom, but somewhat resembles that of "custom" in-ear monitors.
The following is the planned process:
Phase 1
1. Research
2. Mold ear canal
3. Digitalize
4. Test build with cheaper product
If I can successfuly finish Phase 1 then:
Phase 2
1. Disassemble MTW2
2. Digitalize components
3. Modeling modification
4. Build
As of writing, I am at the end of Phase 1 so might have missed a few details and might not be able to go back and collect needed information, but will try to be as detailed as I can.
And if the Phase 2 goes well, I might consider extending the project with Phase 3 which will be another project on its own.
