Wireless Phone Charger - Ikea Hack

I designed this around the insides of the Ikea wireless charger that predated this (http://www.ikea.com/us/en/catalog/products/90318023/) I am working to obtain the one linked to ensure it fits this design as well.

You will need M3 screws and nuts. I just picked some random ones from my hardware drawer, so I am not sure what ones to tell you to buy.
