My greenhouse project is getting out of hand because I've installed a heat pump to extend the growing season. Because of that I need a circulation fan, too. So I modelled and 3D printed a stand for it. I really like playing with geometry but the cool thing it works, too! https://www.printables.com/model/1662611-12-mm-fan-stand-with-thermometer #greenhouse #3dprinting #openscad #bosl2
