I tried finding a model of a jerrycan that can actually be used. I couldn't find one so I designed one by myself.
I went back on iterating my design and added a printable thread.
Personally I use mine to store washing mashine powder detergent. Works like a charm.

I created a custom print profile for this model and added custom supports aswell as variable layer heights at the top to get better quality overhangs. Please use this profile for optimal results.
