Since Cohesion3D is no longer selling these simple adapters that allow people to hook up a generic RepRapDiscount LCD to their $265 dollar controller board and refuses to release the pinout or gerbers, I’ve cloned it based on pinouts graciously provided by Ace_Archer_278521 and marcthijs.
Only 3 parts needed (both can be sourced from DigiKey):
1x PPTC062LFBN-RC
2x 61201021621
You should also edit the config.txt file located on the Cohesion3D SD card and swap pin numbers for panel.encoder_a_pin and panel.encoder_b_pin
panel.encoder_a_pin should be set to 3.26
panel.encoder_b_pin should be set to 3.25
