I was inspired by thefinderp's SiliconGraphics logo, and I wanted to make my own instead of just downloading his (because that would be too easy). Made with OpenSCAD, because it's really easy.
I had some problems with the model detaching from the build plate (since the stock raft was tiny) so I added a big square on the bottom. The bottom half of the cube prints a little rough, but the rest looks great.
