Plunger for soldering paste syringe from KOKI 40g/10ml (and some other paste or flux syringes)

thingiverse

This plunger / piston was created primarily for soldering paste from KOKI provided in syringe (40g / 10ml). It fits as well some other syringes with paste or flux, like in my case: Amtech Flux 10cc. Working length is 80mm (diameter 15.60mm). The diameter is up scaled about 2% so after printing when the plunger is cooled down, the plunger diameter should be about that mentioned 15.6 for gentle snug fit. If used material will have different shrinking properties then the up scaling should be properly changed.
