I've seen this question on several of these case threads (for acrylic, wood, and metal). Rather than ask someone for their CAD files, I think it would be a great start for someone to start a wiki page that details the measurements of a Filco TKL plate and PCB. Screw hole placement and diameter, thickness, tolerances, etc... If someone who has created one of these wonderful designs (or who owns a Filco TKL) would be kind enough to share that info, I think it would be a more reasonable request. That way we have all have a place to start from. The dimensions of the guts, after all, are the basis for what can be done with the shell. Then it becomes more a question of what each person can accomplish from that starting point, rather than putting all of someone's hard work out there, subject to being copied. Just my 2 cents.
