Star nut housing (for printer boards)

myminifactory

I designed this custom nut housing to accommodate a 50mm fan in front of my extruder without obstructing the original printerboard screws. The design can be adapted for any situation where a slim profile nut housing is required, such as replacing a winged nut. The straightforward design can be scaled up or down to fit various nuts. It's initially tailored for UNC half nuts used in my Printrbot 1302, but it should also work with other machines that employ half nuts like the LC+. This nut housing offers a more precise feel when turning the nut compared to the original, while also looking sleek and visually appealing. I'm including both a printable STL file and the original FreeCAD file for your convenience.
