lol you guys shouldn't pressure litster to hand over his file of the case. He's seen this thread, and if he wanted to share them, he will. If not, then just understand that these take a long time to design and cost money to prototype, as well as all the other little things that come with making a product a reality from blueprints.
Everyone wants a nice case for a custom project like this, but I'm betting most won't be willing to pay for it. Just be realistic with prices. It'll cost you anywhere from $200 - $350 for a metal CNC case. The Vortex aluminum case was dirt cheap for $150, and it was clear the quality reflected this. The cost of the actual material is not much, but the time required to program the CNC machine and cutting time on the machine is very expensive. Stainless steel would be very nice, but even less practical for your wallet.
