Need a guide for taking apart the Vive Cosmos controller for cleaning.

Took me 3 days but I finally figured out how to properly open up the cosmos controller (not cosmos elite). Unscrew two star crews out from under the battery cover, then the gloss cover near the joystick and buttons is basically a thick sticker that needs to come off. A razornife will help peeling that off from the lower end moving upwards. Four more screws to take out, one in each corner. After they're off, I just used an old card to shim between the front and back plastic casing, popping them apart. There's a thin ribbon connecting the button circuitry to the handle, so be careful taking the two halves apart. From there all seems pretty standard where else to move forwards with getting back to your trigger area. Good luck ?
