This is a remix of a remix, shortened the threaded section for a wide mouth mason jar. Works well feeding my bees with sugar water for winter, jar no longer bottoms on the bulbed section of the glass. I take no credit for this, all credit to the originator and the remixer. Thanks guys.
Not sure why the top ring looks hollow in picture, ive printed 5 and all have been solid and great. Printed in Cura 4.1.0
