Nut Knob/Handle for Black and Decker Cordless Lawnmower
Description
I needed a replacement knob/handle for the nut used to tighten/loosen the handle of my lawnmower, as one of the original knobs had broken with use. This was modeled after the original knob, and holds a 12.7 mm (1/2") hex nut, but could easily be scaled/modified to accept a different nut. Note that the internal tabs that hang onto the nut are designed for a 7mm thick nut. Print with the knob face down on the bed (as set in the provided file), and if desired, add internal support (I found setting a 2.0mm support X/Y distance in Cura worked well). Also, I recommend 100% infill for maximum strength and resistance to breakage. I've included SketchUp project file, in case you want to work from the source file.
