Based off the PCBs for the DSTIKE Wristband V2. You will need to replace the metal standoffs and screws with new screws and bolts. I used plastic ones for some slight weight savings. You can also modify the LED to point outwards if you have some skill desoldering. The groove in the front allows for the antenna to slip through. I damaged my screen forcing a bad print on the PCB. Don't do what I did!! (-_-;; ) Due to tolerances and variatio in manufacturing, some sanding and adjusting will be necessary to fit your particular wristband PCB!!! This fits mine fine, but I'm not respoible for damage to your device!!! If you want the hardware this is where you can get it: Anyone want to give me a new screen?.... (T-T)
