Xiaomi mi9 standing wireless charging dock(小米9 立式无线快充支架）

This is a phone stand for xiaomi mi9 with wireless charging pad, Xiaomi mi9 supports 20 watts wireless charging, which has been the fastest wireless charging phone in the world once upon a time. However, Xiaomi only sells a wireless charging pad that supports mi9‘s 20 watts wireless charging...I always have trouble putting my phone in place to charge it...and I can't use my phone while charging it using the charging pad.
So I designed this stand, so every mi9 user could make a 20 watts standing
