This small jar can be easily printed without supports. If you have Fusion 360, you can open the f3d file and adjust the parameters to size it as you need. OR, you can scale it in your slicer if you're happy with the stock shape.
Please post your makes, I'd love to see them and you earn Prusa points!!
