Zinc blaster printed plunger rods and plungers for 25mm or 26mm ID PT

Plunger rods of various lengths to maximize the draw. Plungers are to take OD21mmX2.4mm rings but can do other 2mm thick rings as well. All threads are M12. Plungers can be printed at 0.2 mm but for rods it is better to use 0.1-0.15 mm layer height unless you have a die to retouch them after printing. Rods in PC and PETg survive a few games when printed vertically with layer adhesion being the main reason for failure.
