Injection Plunger for Soldering Flux Syringe

thingiverse

A simple piston/plunger helps push the flux fluid out of the syringe easily.\r\n\r\nWhen I received a refill syringe, I realized I had no plunger or original tool to extract the fluid. Notably, the original syringe already features a plug/piston; this design doesn't replace it, but rather complements it by providing an alternative way to push the fluid out.
