Treble Hook Guards.

thingiverse

These are fishing hook guards (Large, Medium, Small) to protect the hook points and your fingers. Easy to snap on and easy to pull off without impaling your finger. The hook guards I have purchased from Sporting-goods stores have been sketchy and easy to get poked. Print these with a .2 layer height and 40 to 50 mm/s with PLA and a 1.4 mm wall thickness and .4 mm line thickness. I use a skirt to get the PLA flowing first no other adhesion needed.
