Here is a video on how to make a bullet lube extruder. It will make sticks as long or as short as you want to make them. I actually made a single stick 2-3 foot long once just to see how fast and long I could extrude a stick of lube. It does work better making short sticks and cutting the sticks off against the all thread.
I will try and post a pdf file of the components and dimensions once I figure out how to make the file small enough to post. I also need to fix a few items on the drawing first, so it might be a little while before the pdf is posted.
I do have some other videos of how the extruder works in case you want to see it in action. I really like using it at first and just made up more lube and melted some back down to keep using it.
I had to scan the plans at a really low resolution, so they might look a little grainy at times on your screen.
Here are a couple other quick links on the extruder:
