First post from a former lurker.
I just recently picked up my 505 and was saddened by a distinct lack of hard case love for this awesome device. Then I got to looking at its measurements and thinking about ideas. I first made a cover for it out of a day planner that I stenciled with Sharpies as some have suggested.
But it was too big and bulky to be carried in the pocket of my tactical vest (No, I'm not a cop but I love the vest cause there is a pocket for everything).
So today I got a bit creative...or destructive, whichever.
I figured out that if you could remove the hub and surrounding ring from the inside of a DVD case, the 505 should fit inside. So about 30 minutes of carving on the inside of the case with a Dremel tool with a carving burr and 4 Velcro dots and I have myself an awesome new hard case. Not only that, but one I can make look however I want, whenever I want, just by printing out a new cover for it.
(Sorry about the crappy camera phone pics)
It wasn't too difficult once I figured it out. It is, however, messy and noisy as can be. It sounded like a bird being tortured (not that I have ever tortured a bird) so make sure you don't so this while others are sleeping like I was going to do last night. I don't need to remove it to plug in the charger or USB cables. I will have to remove it to take out the SD card but that isn't something I would do that often and I have gotten frustrated as the SD card has been accidentally pushed in my pocket a couple times while in the stock cover. So this case should prevent that as well. The Velcro dots keep the unit from actually touching the back of the case. I have considered adding a few dots of the felt side to the inside of the front cover to help cushion the unit as well, in case of a drop.
Advice? Suggestions?
