Hustler Super-Z mower deck cover knob

thingiverse

This is a replacement knob for a Hustler Super-Z deck cover. It will most likely fit many other models/brands. It utilizes a 5/16 nut that just pushes in place, with an optional plug to close it out. I've included the STL file as well as the FreeCAD file, in case anyone wants to change it at all. It should be printed with supports or the overhang will not print correctly. I designed the plug with zero tolerance, but I ended up printing the plug at 98.7% to account for rough corners/bad printing, etc. it pushed in perfectly. If you’re going to use this design without the plug, I would reduce the scale slightly because the nut fits without much force, and may push back out before it starts threading on the bolt. If you print this please post a comment or upload a "make". I'd love to see what I've designed helping someone else.
