I recently modded my iPod Video and wanted a travel case for it. It's hard to find accessories for electronics this old so I designed and printed one myself. I dialed the tolerances in to perfectly fit the iPod Video (4.1 x 2.4 x 0.43"). The fit is quite snug because I didn't want the iPod to be able to move at all inside the case and I wanted the case lid to stay on when it's in my bag. I printed it in Prusament Galaxy Black ASA and I think it turned out great!
