Are you behind snap2print.me? Looks super cool. A good idea for sure.
I could almost guarantee what we were shipping was more fragile than your printers, (not a pissing contest) but it was precision instrumentation that needed to not get jittered around. Pelicans worked great for us. http://www.pelican.com/us/en/
And they arent even that expensive.
Product looks really cool!
Also, there is a typo in your FAQ, second question (Can I print without adding the printer as a friend?), account is misspelled in the answer.
