I lost one of the mirror nut caps on my gz250 motorcycle, but luckily, I still had the other one!
I modeled based on the measurements of the old one, to get this new one.
I will probably do some other remixes, as this unused real-estate on my bike could potentially use some flair.
For now though, they're protecting the mirror nuts from the elements.
I printed these on the "High" setting defaults.
The nut cap should have the base facing up (as-is in the .stl file), with no supports needed!
May need to sand the top a little bit as well as the edges.
It is slightly larger diameter than the original, but thats just so its easier to take off (it fits very snugly though).
