I have bunch of wide mouth, round bottom mason jars (Thanks COVID!) and I want to stack them so they don't look like they are testing the limits of friction and gravity every time I open the cabinet. So, I spent more time than necessary and designed a way to stack them that doesn't cause me unnecessary stress and anxiety (as I have enough of both already). Hopefully, the reduced stress can be shared, albeit slightly, via this model.

I raise my models to be self-supportive so hopefully, you don't have to use supports either. Especially, when printing in the right orientation (the center support facing down). No judgements if you want/need to use them.
