Caliper Desk Hook

I made this quick caliper hook to go on my desk and figured it wouldn't hurt to share. This is designed to fit on a 15mm thick desk surface. I made the hook 2mm wider than should be because my printer doesn't have great tolerances. If need be or if I feel like it, i can make more iterations to make it better (or you can make one yourself, this only took like 15min excluding print time)
