The sheath deals with that. Friction/screw tension makes it harder too. You're right though, there is no lock to keep it closed if it's not enclosed somehow.

You can change quite a lot (pivot & blade are original)
Proteins are made from amino acids, same as words are made from letters. If you eat a protein source that's short on some of those letters then you need to mix it with a source that has more of them... Otherwise you can't create all the proteins that you need. (It's a bit more complicated, but that's the bit that you need here)
Have you done any calibration, or just gone straight to printing?
Wow, that's a big 3d printer! (If you've ever printed spaghetti on a smaller 3d printer then you know)
