Summary

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/

Instructions

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.

I would like to point out that many motherboard designs use these screws as a ground connection, and that obviously won't work with a plastic part. My guess is that this would work flawlessly 95% of the time, but if you find your computer being less than 100% stable while using these, try some ordinary metal spacers.

That being said, I think this is a great Thing, and I may well find myself using it!

Interesting, I'd not considered that. I made it because I needed to support one corner of a board for which I'd butchered the metal spacer. I suspect it may vary from MB to MB, but it is possible that having one of two plastic won't bother you. Some MBs I've bought have come with a combination of plastic & metal, and no indication of a preferential placement.

I've run at least a hundred MBs out of the case, just sitting on my desk, obviously without grounded screwholes, and while some of the have worked and others not, I doubt this was ever the problem.
All ground connections on most PCB design are typically connected together, meaning that no single one of them is crucial for the basic function of a ground connection; that is to lead the positive voltage back to the source. However it get's more complicated when a ground plane is used for signaling; in that case even some minute resistance and/or capacitance can reduce signal strength and accuracy, basically meaning that if ground is only available through some roundabout route the risk of corrupted signals increases slightly.
Basically don't worry about it, but I thought it deserved mentioning.
