Hi.

DIY ATA style?
A shameless nudge towards my DIY case thread

.
Making a custom case for Epi LTD Explorer
There's been rumours that some bags actually are big enough for Explorers, but I haven't seen one in person. Nor would I be comfortable with one. Too risky IMHO.
A DIY soft case ain't that hard to do either, I'm sure that someone who know can teach You how to sew.
Materials are expensive as hell, especially the good quality zippers, but that's how it is.
Regards
Sam
