So, the cat likes to sit on the top of the computer and has an annoying habit of turning it off when she jumps off. 5 minutes in OpenSCAD and 10 minutes printing a couple variations and I think we have the perfect solution!
And that is the coolest thing about 3D printing. It’s not a revolutionary device, it’s not really useful for anyone but you due to the location of the USB ports, but it’s a perfect solution for you which you could whip up in fifteen minutes.
Of course… a little tape and a piece of cardboard may have worked, too.
When the only tool you have is a hammer… It’s a symptom of owning a 3D printer, you think how you could print your way out of any problem.
But then you can’t see the power button! OK, in reality that is totally true; it was more fun this way though. 
well…this is an improvement on the old fashioned method of putting the cat in the freezer till he learns to stay off my computer
Good idea, thanks for sharing with the rest of us.
