About this 3D model
This Thing holder (clip style) used to attach a 50mm x 15mm Fan to Nema 17 Stepper Motors. This provides needed cooling to my stepper motors and is small enough to fit on my Mendel. Other fan things I have seen on thingiverse would not fit on my steppers, they all hit something or other preventing installation. If you use this thing make sure your Fan is 15mm thick. I used an M4 bolt to mount fan; I drilled out the hole a little smaller than bolt so it threaded into the plastic. Installation was plenty tight to keep fan at desired angel. Added Second Clip that wraps around entire Stepper, using this for my Extruder Stepper.
