FritzBox Fon C5 Stand

The FritzBox Fon C5 has a great speakerphone, but the speaker is on the back and so the sound is at time a bit unprecise.
To remedy that I designed this stand and it works great.
The stand has two slots, one holds the back plate at 20° and the other at 45°.

UPDATE:
I updated the design, so the Fritz!Fon fits more snuggly into the stand.
