Air Filter Cover Knob for Briggs and Stratton
by RebelTaz

This is a common style air filter on several Briggs and Stratton engine models. From what I have found, it can replace part numbers 844618 / 691985 / 491875 and probably others. For this, you will need a 7/16 hex nut with the proper threads to match your stud. Simply print the parts in the orientation given, drop your nut into the knob and press the plug in above the nut, with the beveled end down. This locks the nut in place and give the knob a more finished look.

For strength, I recommend 1.6mm walls with 40% triangular infill.

I am a self-proclaimed know-it-all. I will tackle any project regardless of my experience, or lack thereof. Always ready to learn something new. With over 25+ years experience in electronic repair and 10+ years experience in small engine / ATV / motorcycle repair, there is nothing I can't fix, modify or build.

Why a pepper? In case anyone is curious as to why there is a hot pepper embossed into most of my designs... My nickname is Pepper and that little pepper logo is a hell of a lot shorter than "Copyright © 2017 by Derek J.G. Tombrello" which is how I usually sign my work :)
