Bee Feeder and Waterer

I printed two of these for my wife and after giving them to her she asked if there was a way to make it so that the Ball jar stays attached. After considering some options and messing with it a bit I decided on using a thumb screw to hold it in place. I just drilled and tapped 1/4" hole and screwed in the thumbscrew, it works but it's not the best solution.

After she asked for two more I decided it'd make sense to modify the design to include threads so that's what I did, Bee Feeder and Waterer Threaded is available for anyone who what's this design with threads.
