I recently picked up a wireless charger for my Galaxy S7, but wanted a stand for it. Built this up real quick in Tinkercad. Apart from the placement of the pad, there's nothing model-specific in the stand, it'd probably work with other phones that have a similar charging window.

I'm using the "Pictek Fast Ultra Slim QI Wireless Charging Pad here:

I printed mine in laywood, and used a few drops of hotglue to secure the charging pad in place.

Snap in the charger and you're good to go.
