Dock for Nokia DT-900 Qi-charger

I wanted a dock for my Nexus 4 phone, but thought the original Nexus Charging Orb to be too expensive. So I bought a simple Nokia DT-900 Qi charger and created my own dock arround it.

Now all that remains is a NFC-sticker and to find something to prevent the phone from sliding off. I used some double sided scotch for the pictures.

I am sharing a pretty accurate model of the DT-900 charger itself here, in case you want to build your own dock; https://3dwarehouse.sketchup.com/model/4cd47586064f801fb08c032bedc99529/Nokia-DT-900
