This is a lid used on a Fedco Forestry Fire sprayer, similar to the one on this amazon listing: https://www.amazon.com/Fedco-190387-Poly-5-Gallon-Orange/dp/B00FS316VQ/

I modeled and printed this after a hole was broken on the original lid, and did not know where to go to order a replacement.

Modeled dimension-for-dimension in Fusion360. I am uploading this on the off-chance someone may have a use for it.
