- Two plates of metal (or plastic)
- glue-gun / super-glue
- Electrical tape
Step 1: Layout of the headset
Luckily the answer/call button was located roughly at the center of the piece. (saved me the hassle of relocate it and solder..)
Step 2: The casing
I decided on three screws to hold the piece together, one in the front and two at the back.
Step 3: Making holes for the speaker
Step 4: Fitting the headset in the casing
Then I fitted the circuit board so that the answer button would match the hole in the metal tag and applied a reasonable amount of glue.
Step 5: Put it all together
When I had tightened the nuts I cut the top of the remaining screwes off.
