Here's something I made today, I had a little drawstring bag that was the right length to fit the dingoo, but was way too wide.
I turned it inside out, cut the bag along the side so it was a good fit, and sewed it up.


I think it looks pretty good, it's a nice snug fit, which is lucky because I cut it by eye and sewed it a little bit too small... luckily the stitching stretched a bit so it fits nicely. I'm hoping to customise it further, maybe sew some kind of patch on it, a belt loop or maybe a stencil design.
The dingoo really needs more accessories. I for one would be happy to pay for custom skins, cases or maybe an attatchment similar to this one for the psp:
