Kaimana Mini LED PCB to 30mm Crown 202 Adapter

I had this uploaded elsewhere and am just bringing it over to here:

Paradise Arcade's Kaimana Mini LED button system was designed with the Brook Fighting Board PCB and Sanwa buttons in mind. Many of us use 30mm Crown/Samducksa SDB-202 MX buttons in our fightsticks however, and there was really no good way to attach the J2 RGB LED PCBs to the buttons.

Previously, I was just double-side taping them to the side of the buttons which worked OK, and some people put them at the bottom of the button, using the wire connection to provide enough friction to keep the PCB in place.

I decided to make a slightly more secure and elegant solution to adapt the Kaimana button LED PCBs for use with 30mm Crown 202 buttons. This should be all friction fit, just be mindful of the connectors on the PCB. Your PCB may have some extra PCB material on the sides of the round parts of the PCB from when it was manufactured, so that will have to be sanded off so that the PCB will fit into the adapter properly.

My particular fightstick is a very heavily modded Madcatz TE, so these adapters were made with my stick in mind, so your mileage may vary.
