I lost 2 of the bolts that hold my fold-able lawnmower handle together. After searching for Things, I decided to try Tinkercad.com and design my own. Nothing fancy here, just practical.
I thickened the top, bottom and side layers to give a bit more rigidity. I purchased the nuts and bolts from Home Depot for just a few dollar$. I could refine this piece, but it's an outdoor item I won't be using very much. It is what it is.
I printed the knob with PLA and it lasted for a whole year. I would recommend using PETG and giving it an infill of at least 50%.

UPDATE
After a summer of mowing my lawn, I've decided to update the handle to fit my mower better. The file with "final" in the title is the updated mower knob. I have also found better bolts from Ace Hardware that have a curved head and stay tighter in place.
The nut fits really snug, just make sure your bolt is long enough to fit through the knob and handle.
