Tiny Boy Fabrikator 25mm feet to hold an 80mm fan in the center

Hi, I was bored while waiting for solidworks to install so I made these feet up in sketchup which became pretty handy as the electronics and especially the stepper motor becomes really hot and skips steps.. with this printed plus an 80mm 12v fan, she hasnt missed a beat.. takes about 1.2 hours to print per leg. The G code included is from slic3r and is 30% speed on the first layer and 5% infill for the fastest possible print on these little bad boys...
