Step 2: Next, carefully cut out the plastic wall of the heart rate sensor using a sharp object. Be precise and take your time. Step 3: Using dichloromethane or superglue, attach the clear plastic part back together. I used PLA plastic, so I needed to use a special kind of glue that works well with it. Be careful not to let any excess glue get on other parts of the watch! Step 4: To keep everything in place, I used a strong clerical gum to hold things together. This made sure all the parts stayed where they were supposed to be. Step 5: Now it's time to attach the NFC module. Make sure you follow the instructions carefully and don't mess anything up. Step 6: Installing the motherboard is a crucial step in building your Moto 360. Don't skip this part or your watch won't work properly! Step 7: Finally, assemble all the parts together, making sure everything is secure and in its proper place. Be careful with those fragile wires - they can break easily. Important note: The holes for the strap and microphone were made using a hot clip, so be careful not to burn yourself or damage any of the parts.
