Comandante to Ball Jar adapter

Print shown used filamentum nonoilen filament, as that's supposed to be food safe.  I will likely have this printed in aluminum or stainless steel for long term use.  The whole point of this was to not have to buy comandante jars that don't fit over 40g of beans, and their glass jars shatter easily.  Ball jars with normal lids are much easier to get in USA.

Demo print shown used prusa viva la bronze.
