I love thruit00's Active Cooling Fan Duct v2, but only want it on my printer when I'm going to use it! (It obscures the view, and I like to keep an eye on what's going on!)
So I originally mounted his active cooling duct with longer (20mm) screws and springs so I could easily remove it. But I found that the little clips were a bit difficult to get a grip on with my big hands and fat fingers, plus the clips wobbled around a bit with the springs.
So I designed and printed these Spring Clips. They're designed to use a 20mm screw and a spring about the size of a spring from a 'click' pen. (I got my springs from a spring assortment I bought online)
Let me know what you think!!!
