Bug-A-Salt Replacement Plunger

My Bug-A-Salt version 1 had a broken plunger so I designed and printed a new one. The plunger is printed in 3 parts and uses the gaskets from the original plunger. You will need a 30mm M3 screw (1/8" is very close) and matching Nylon Lock Nut. This version is sturdier than the original and compresses the spring about 10mm more so you get a slightly stronger shot.

OpenScad source included if you need to make some tweaks. I am not sure if this will work for any version other than version 1.

I recommend printing this in PETG 100% infill and while you have it apart, lube it up with lithium grease.

Thingiverse refuses to render thumbnails of the models so I am attaching a picture.
