Damn, that travel pack is awesome!! I like the way you've got the foam hollows cut out exactly for the object that goes with each hole. That looks very nice. Should register as a supplier and sell custom made ones to suppliers 
Electrovapors and other suppliers might be interested in Leo->510 adapters and 510->Leo adapters - there are only 2 places that sell Leo->510s currently, and nobody makes 510->Leo connectors at the moment. If you've got access to fabrication equipment the Leo->510 adapters are going for around $12 a pop.
