Clip mount for Magene H803 optical heart rate sensor

Clip mount for Magene H803 optical heart rate sensor, so it can be mounted on a sleeve, a bib-short strap or an arm warmer directly. I designed this clip mount so I can keep using this 45hrs heart rate sensor for endurance rides without using its original armband that triggers my sensitive skin.   

Model can be found here: https://www.magene.com/product_h803.html

for installation, please slide the heart rate sensor into the clip.
