This is one of those cheap ebay Qi charging pad. Crack it open, move everything from here...
...to my 3D printed dock.
Slide coil in, PCB is held with double sided tape. Pretty straightforward.
A bit of PCB is trimmed off to make space for the connector. I did cut off the speaker, it's too loud for me.
Messy inside but hey, you can't see them!
And the back:
I have my SKP (Google SketchUp) files attached below, feel free to use or modify!
If you're actually going to send these files in for printing, make sure you double check all measurements!
It appears that some of you may be interested in making one. I just made this model public at Shapeways http://shpws.me/oi3O.
This is designed to fit parts from "GMYLE (TM) Wireless Charging Pad Powermat Mat Charger". Other models may not fit and you'll have to modify.
You can download the model and make the walls thinner, engrave some text/logo, etc. The less material the cheaper it is.
Putting it together is very straightforward once you have the parts in your hand and use the the pics above as references.
