Oil Change Container Plug

This is a replacement plug for an 15qt oil change container. The brand of my particular container is Blitz (see picture), but I think it might be sold under other brands as well.

I was inspired to create this after finding the spout cap for this same container on thingiverse. https://www.thingiverse.com/thing:2938710

My design has a couple of advantages over the original plug (see picture):

1) The flange/seal is solid where the original flange is thin and breakable.
2) The "knob" on my design does not have the "pockets" on the top that catch oil and make a mess.

The "latches" on the end are intended to keep the plug in the open (out) position while draining the oil but still attached to the container. You have to apply a little force to get these latches through the plug hole. If you prefer to simply remove the plug entirely while draining oil into the container, then you can break of the latch tabs *before* you put the plug into the plug hole.
