I should probably know this but what is the larger threaded hole for? Is that for some sort of filling attachment or something?
Also, I use one of these to clean up prints. Be careful though, its sharp as fuck all. I read the reviews that said as much and was not as careful as I should have been and yep.. the reviews were not wrong.

There are also a few other methods to clean up prints depending on the materials you are using. Like acetone to "smooth" it out.
I ordered the noga SP770. Pretty much the same tools but all with separate handles. Seemed like it would be easy to just have them sitting on the desk to go back and forth on tools without having to open and close them into a handle.
So the threaded thing on the side is the cap for closing the container. that way it can't get lost, it's attached to the spout.
Oh, that makes sense. I have seen those before. I knew I should have known what it was x.x
