This is yet another wireless charging stand. I designed it for my Samsung Galaxy S6 smartphone with an inexpensive, generic Qi charging pad. My specific pad was branded the Audew Q5 (http://www.banggood.com/AUDEW-Q5-Universal-Qi-Wireless-Charger-Charging-Pad-Transmitter-p-985122.html). My phone is protected by a relatively bulky Otterbox Commuter case, so most other cases (or bare phones) should fit as well.
The design is generic enough so that almost any smartphone will fit mechanically, although I can't guarantee that the charging pad will be positioned correctly for models other than the S6. It might even work with the newer S7 (confirmed by 1 maker so far). Works on my new S8 as well.
This is my first from-scratch design. I took on this simple but useful (at least to me) project as a vehicle for learning SketchUp.
