THIS IS A STATION FOR THE CHARGER OF THE XIAOMI AMAZFIT BIP WATCH
It has a simple shape so you can print it easily (on its side).
Remove the support material.
Pull the usb cable through the hole.
Take the charger and twist it in the socket. It has to fit tightly.
If you did it well the charger can not come out.
Accouracy and catching depends on your printer
0.1 layer height recommended for accurate curves
Removing support material
I've used Fusion 360
Step 1. I tried to design a shape like the original charger.
Step 2. I made an easy-to-print model of the station I imagined previously.
Step 3. Using the combine tool to cut off the body of the charger from the station.
...and a lot of scaling to reach a perfect size.
