Uploaded this for Haavix on reddit- this is a license plate light meant to replace the taillight attachment on the Yoshimura tail tidy for the GSX-8. This is a little involved and a really specific use case but since they asked I might as well upload it.
Notes:
Though it obviously fits perfectly, I didn't originally mean to upload this so some of the stuff like bolt holes might need to be cleaned up with a drill to get the bolts to pass through cleanly.
On mine, I weather sealed it with medium CA glue on the seams. It has survived a couple washes without shorting so I think it works fine.
I used PETG filament, and clear PETG filament for the lens, though if you have trouble printing the clear lens well, the slot where it attaches is a rectangle so you can probably find a piece of polycarbonate or something like that to stick there instead.
These are the stainless bolts I used, I used the washers and lock nuts that came with the Yoshi tidy, but any stainless lock nuts and washers should be fine.: https://www.amazon.ca/dp/B0CJB68QBP
