This is cheese, butter, curd churner machine. This is manual machine. You have to drive by hand. 3d printable stl file attached. All parts are in a single stl file. 3d editable file can be provide.

You can put top part of the assembly on the any jar. Just you have to make a hole on the top of the cap. I attached the machine on my designed 2.5 litre glass jar.

You can choose other types of handy machinery too. You have to contact with me for more details. If you found any difficulty please contact with me.
