Model Purpose: Used for repairing screen mura and contact issues on the first generation Pebble watch. If your screen can be restored by padding or pressing, you may try this method for repair. Usage: After opening the back cover of the watch, fit this small part over the bulge that presses against the screen, then reassemble. Printing Recommendations: It is recommended to print using TPU material, which is less likely to damage the flex cable. I used a hardness of 95A, but choosing a softer hardness may yield better results. When printing with TPU material, please use a printer with a direct extruder.
