I felt this deserved a new thread since I'm pretty proud of this accomplishment, I created a replacement Internal Chassis (the part that holds the drives, speaker, power LED) for the extra-wide pizza box Macs such as the Centris/Quadra 610 & 660AV, Power Macintosh 6100/60, Workgroup Server 6150, Performa 6110CD, 6112CD, 6115CD, 6116CD, 6117CD, & 6118CD. I've only used it on a Performa 6116CD, but I am guessing it should work on those other models. I actually have two Performa 611XCDs and both arrived with a heavily damaged internal chassis. The first one I figured was from poor packaging, but the second one was from someone who did an excellent job packaging it and it still arrived heavily damaged. I even damaged their internal chassis further during disassembly, all the while taking care to try and not do that! I've been really wanting to get into 3D modeling and printing, so here I am. This is my first time 3D modeling something to print. Please be kind. 
I used Blender because I want to also use it for 3D modeling for game design.
I've uploaded the STL files to Thingiverse if you're interested: https://www.thingiverse.com/thing:6989132
