Đầu Piston Lynx Hotfix (Lynx Hotfix Plunger Heads)

A slew of plunger heads with varied groove diameters to expand the o ring if yours doesn't seal.

Ideally your o ring floats and make contact with the pt without this because this can also introduce a slight vacuum at the end of the return stroke.

Versions without the debossing included as a zip if you are concerned about a single layer missing a little material.

Tip: I used binary search to dial in the radius when I previously adjusted my seal. Print an option in the middle, see if it's too tight or loose by pushing it through the pt with an o ring, and set that as your new upper/lower bound.
