TPU Lynx Plunger Head

I used the tighter plunger in the original file set so it should be screwed on the threaded rod. I printed mine in foaming TPU with 5 walls and 15% gyroid infill. For lighter spring loads, 3 walls & 10% infill work as well, just beware of squish/flex under high spring loads if you go this route.

Plunger head end thickened for better contact on the locknut.
