I've got an old white macbook and a newish retina macbook pro. Typically these live on my desk stacked on top of each other, with keyboard/monitor/mouse plugged in. My cat likes to sit on top of them because they are warm. She also likes to chew on nearby cables. This is a problem. So, here's this Thing to stand them vertically! Kitty came by looking for her warm spot, but didn't stay long. My desk is now clearer, but also more lonely. ... success?I modeled this in Inkscape and OpenSCAD. I roll like that. If you want to make your own changes: I printed my copy on a Replicator Dual with 0 extra shells, 10% fill, 0.2mm layer height. It took quite a while. My Replicator is semi-enclosed, but I had some issues with cracking. Since I don't care too much about the aesthetics, I just hit it with a heat gun to fuse the cracks together afterwards.
