First model, I have not printed this. Looking at it in fusion360 it should be good to function. You will need supports to print.

Considered making a version where the blade and guard are 2 parts for easier printing, might do in the future.

Should be just enough clearance where you don't need to be super dialed in to have it come out of the sheath easy, but not fall out on its own. If you want to be sure just size up the sheath by 1% or so.

Update 6.22 - Fixed the sheath, redditor Dapper_Pea was nice enough to point out I messed up hollowing it out correctly.

Update 6.22 - 2 - Added another sheath style more like the source on reddit, had a wider look to it.
