Designed a Small Knurled Extruder Knob since the ones out there take up too much space and if you are using the entire height of your machine, this is less likely to hit another mod. I also found that this smaller form factor makes it a lot easier to feed filament into the extruder, and you can still see what you are doing.

The print is detailed enough so that you can use whatever layer height you want to, but i have personally only tested 0.16 mm

I made this because it had a practical use for me, and i was able to practice some new modeling techniques, so any feedback is much appreciated.
