I wanted to print a sega case for my Pi and could not find one. I found printandplay2k's genesis low poly console which although is meant to be a pi case, does not actually work as a pi case... I cut the guts out and rebuilt it for a pi 2
The top face needed replacing to the round dome shape and new text added so it would print out right for the size.
It's a snug fit and does not lock closed all that well, but I take mine in and out of cases alot so I didn't want it to be hard to remove.
I printed the top cove upright, as it requires less supports and the text comes out much cleaner than a horizontal layer spread.
