Case for OMRON M2 Tonometer/Blood Pressure Monitor

Upgrade and protect your OMRON M2! 🩺⚙️
This project is designed to wrap around the main body of the OMRON M2 tonometer, protecting it from everyday scratches and minor bumps. Whether you just want basic protection or want to build your own automated blood pressure logger, there is a version for you.
 

Choose Your Variant:
Variant 1: Snap-On Shell

Variant 2: Secure Clip-On Shell

• Features additional side clips to lock the top part firmly in place.
• Requires 4x M3x30 mm screws for a secure and durable assembly.
