MoraKniv 120 and 122 blade cover

I had an unfortunate accident with my Morakniv and had the stock knife sheath slip off and the knife stabbed me.  I came up with this idea to make a cover that would not slip off when you are putting it away.

Fits both 120 and 122 style Morakniv wood carving knives.

I print these in TPU. Let me know if a different material works for you.
