Plunger replacement for Presso hand press espresso machine

This is a replacement plunger for the Presso hand press espresso machine. I printed this in Taulman Tritan to make it as food safe as possible. No guarantees on food safety and bacteria between layers and in micro holes. I'm hoping that food-safe printing will advance very soon, let me know if you have any tips.

Also feedback is appreciated on the size and fit!
