CPU display cases, gen. 3

A slight tweak to the generation 2 designs that features a slight protrusion on the inside of the lid. This makes it much harder for your precious chips to fall out of their cases when you're holding them upside-down!

Separate lid files have also been included, as the bottom cases are 100% identical to gen. 2 cases.

The 35mm x 35mm cases fit Socket 478 processors only as far as I've tested, while the 40mm x 40mm fit almost any modern AMD desktop CPU. The 50mm x 50mm cases fit everything ranging from Socket 5 and 7 CPUs to Socket A and 370, not counting the Slot-1/A designs that Intel and AMD used for a short time. The new 37.5mm x 37.5mm cases will fit LGA77x and LGA115x CPUs from Intel, meaning that a wide range of Intel's mainstream desktop processors will fit in this case size!

Instructions for proper dimensioning for slicing programs are given in the relevant "case notes" text files! If you feel like these cases don't protect your CPU collection well enough, there's enough
