Backpack for the Mi Power Bank 10400 (Xiaomi Powerbank). Since I am often on the go and need a wireless charger both my watch and other QI compatible devices, I created a small little back for the Power Bank which fits a standard "hockeypuck" eBay QI charger.
Printed with ColorFabb Dutch Orange 1.75 PLA. First layer on 205c and the rest on 200c. 20% infill @ 200 micron.
I used two strips of double sided tape to attach the print on the Power Bank. Used it for a couple of weeks without any problems of getting loose from the charger.
