Leyden Jar Stand for Crystal Radio

Leyden jar base for 2 1/2 inch dia. jars from the dollar store.
I'm designing a crystal set using these instead of capacitors.
Put foil inside and outside of jar....Then make contact with inner foil to top electrode.
or
Put foil on outside of jar then fill jar with salt water then install top electrode to hit water.

multiply scale by 10 in Cura for proper size.
This was designed in inches and Cura doesnt read inches.
