Treble Hook Snell Tool

This is a set of tools that can be used to tie a fishing line to a treble hook (snell). While searching for fishing accessories, I noticed a tool to safely snell a single hook, but nothing for a treble hook. I designed these tools to provide the same function for treble hooks. The shank of the hook fits into the slot and the eye of the hook should stick up out of the top. The tool is designed to keep the points of the hook away from the top. I printed these in PLA and they seem strong enough to get a good knot.

There are four sizes, designed for treble hooks from size 2 to 14. I am hampered by a lack of larger or smaller treble hooks. The tools are sized to fit the following hooks:
Large - size 2 or 4
Medium - size 6 or 8
Small - size 10 or 12
Tiny - size 14 and maybe 16 (I don't have any 16)

This was designed using Fusion 360.
