PC Motherboard mount
by fantom, published
This is a replacement for those metal or plastic spacers that are used to mount a PC motherboard inside an AT or ATX case.
Design removed and replaced with the flat disk you see, feel free to email for the original if you want it. See following link for details http://traverseda.wordpress.com/2014/05/23/makerbot-blatently-steals-and-patents-a-community-design/

I found that the best result was obtained by slicing with many shells and no fill, and printing upside down so that the screw thread is the last portion to print.
The SCAD file can be fiddled with if your motherboard happens to have a different size.
