This is an improved version of my original design for Mi3 Band - Adopter (https://www.thingiverse.com/thing:3449213). Size of adopter is increase to ensure good contact and the proportion of top and bottom part were adjusted such that it reduce the gap when closing of two parts. Due to the design, the Mi3 can fixed/sliding along any position of your selected nylon band.
There are two options for using this adopter.
- Use with the existing automatic watch (i.e. Front of waist is automatic watch and back of waist is Mi3). Two watches can be used together and pulse can be measured at the vein of hand.
- Use the any nylon band with Mi3 (i.e. Core unit in front of waist) such that it is lighter in weight. Pulse can be measured as in the recommended way of Mi3. It is more easy to put on the nylon band than the silicon band of Mi3.
For thicker/wider band, the opening of bottom casing shall be adjusted. For the watch without nylon band, it may be mounted with next design as shown in last photo.
