I bought a headphone switching board from ebay (https://www.ebay.com/itm/3-5mm-Stereo-audio-Switching-Board-socket-2-IN-1-OUT-1-IN-2-OUT-A-B-Group/121863261446) but its without a case, so I created one.
You will need 2 piece of M3x10 bolt too.
For the lid, color change after 0.4, and 0.6 mm (with 0.2 layer, its 2 layer)
Just put everything together, and screw in the bolts from bottom. You need to screw in directly in the plastic.
