Diffuser for onboard K10D flash

Been using the onboard flash a bit and decided to see what I could find in the way of a diffuser.
Anyway, here is my first effort.
Pics taken straight out the camera and just converted to jpeg.

With the Diffuser :




What is the diffuser :




It's the plastic contact cover that comes on the K10D battery.
Sits on there very nicely with a little encouragement.

The K10D is certainly not as sexy from the front though ...

I used an old film box as a diffuser on my Ds. Can't see for spending silly money on such things when there is perfectly good free stuff to use!
Well done for spotting it would fit! looks better than a film box in any case.

I tried your solution also sockpuppet. But over here in the Netherlands it seems the original Pentax battery contact cover has another shape, as yours in the picture. Thus.........of no use, I am sorry to say. I really was pleased with your idea, but....
