Propeller Spinner (M5)

cults3d

If your motor has an M5 screw to mount props, simply put these spinners on top to route air nicely around the motor. It's also beneficial to mount your copter upside down for maintenance or to (un)mount your battery. Internally, the 10mm length of the M5 bolt in your motor fits snugly over a standard bolt. The bottom 4mm are slightly larger to accommodate a nut, allowing it to protrude up to 6mm above the nut. You can adjust these dimensions within the mesh if necessary. When transitioning from nut to bolt during layer-by-layer printing, some support is required unless your slicing program can expertly handle such situations. I've included a version with small internal support that can be easily removed using pliers. A blender file is provided, featuring a raw mesh with separate support object.
