Phone stand where you are able to place your wireless charger and use it while cooling down your device by putting a cooling system where slots are. There's a few electronic components you'll have to purchase.

Items:
10x1 CM (MAX) WIRELESS CHARGER
30x30 MM 5V FAN.
D14.5 MM MINI ROCKER SWITCH
USB CABLE
PROTECTION DIODE (OPTIONAL)
SOLDERING SKILLS

NOTE: There's NO need to place supports because it already has some where there should be. Just print it without adding any structural support, it does work.

Sincerely appreciate your tip.

Best,
