EFFALO designed these nifty geodesic dome connectors.  Since you need a ton of these parts, they started a distributed manufacturing experiment to crowdsource the printing of a dome.  They're offering $2 per connector and whoever sends in the first usable part gets to pick a microfunding project to donate $20 to in your name.  I thought it would be pretty cool to make a personalized part to differentiate my contribution.  So since the connectors were already designed in OpenSCAD, it was pretty easy for me to add my OpenSCAD bitmap module and emboss my initials and my logo on top.  I released my mashup script so others could do the same with their initials.

I ended up being one of the first people to send some - I tied with someone else.  So I got to choose a project to donate $10.  I decided to send it to the OpenPCR project.  OpenPCR is working on making an open source Polymerase Chain Reaction machine for under $400.  Commercial machines cost $4,000 or more.  It could help do for biotech what MakerBot is doing for 3D printing.  I don't know if I'd ever make one myself, but I might just so I could feed it into an Open Gel Box and take pictures of my DNA in my basement.  HA!  How awesome is that?  There is a great video overview.
