<p>Your printer should have come with a bunch of tools, one of which is a thin wire with a rudimentary handle, and the pointy end stabbed in some foam/polystychrene for protection.  Is that what you tried inserting?</p>
<p>It is a very small hole in the end of the nozzle, and you need it hot else the whole thing is blocked with hard filament.</p>

<p>I’m new to the printing scene and got an Ender 3 Neo Max. I printed a couple of models with no problem, then the filament just stopped dispersing. I figured I had a clog, so I tried to shove something up the nozzle and it wouldn’t go in. I disassembled the piece and took the nozzle off, put a new nozzle on, and the filament still wouldn’t disperse. Any tips?</p>

Sorry your question was closed. We need more detail. You put a new nozzle, so I assume that was not blocked. Thus it is probably blocked somewhere else. Do you know where it is blocked? Maybe further descriptions and some photos would help. Please [edit] and update your question, and then it could be reopened. Otherwise the answers will just be broad guesses. I would have added an answer myself, suggesting these [tiny "drill bits"](https://www.google.com/search?q=3d+printer+drill+bits), but they are only useful for blocked nozzles, which doesn't seem to be the issue as you've replaced it.
