Rifled potato canon

Rifled barrel potato cannon to get that sucker to go farther!!! This is a work in process as I am just now printing one of the sections. I will be posting more sections as I design and test them.

Make sure you don't make it too high for your printer!

Plunger is an example of poor OpenScad but it works...

CHANGES:
Jan 3, 2025: Added version 2.0. Now using triangular rifling instead of square. Height is now 200mm for shorter printers
