Gerber Axe Insert

An insert for the Gerber Axes with hollow handles, which makes it so you can load up the handle of the axe with all sorts of survival gear, fishing hooks, matches, Bic lighter, car key, etc. or whatever you can fit!
My friend wanted me to sharpen his axe while he was away and i thought i'd surprise him with an upgrade. I asked if there was ever a knife that clipped into the handle or anything and he said it came like that, so i looked online and most of the hollow handle Gerber axes dont have this or a way to turn it into a sruvival gear container, so i eyeballed the dimensions and designed this. It's not perfect by anymeans but it's effective.

Instructions:
Print 'insert B' if you dont want to fiddle with getting it to fit much,
-but if you print 'insert A', Use 5-10% infill 2 shells, then take the printed part and dip the end which would be inserted into the axe in some boiling water (i used a tiny glass bowl for ranch or other dipping sauces and microwaved it for about 30 s
