Cobalt 40v Weed Eater Bump Knob

thingiverse

My Bump Knob broke and Lowe's told me they were on back order. I'd only had it for 3 months, so I decided to make a new, much more heavy duty one. Is a little bit tight on the first use, but after about an hour it works perfect. I recommend using 6+ top layers so it will last being smashed into the ground over and over.
