Sprout jar lid

Jar lid for sprouting.

This should match the thread of a regular jar with **80mm outer thread diameter and 85mm outer jar diameter**. The ones I have at hand, all have six threads. The support nicely fits a 85mm diameter jar and probably could work for thinner jars. It holds the jar at 45° and should easily support a 110mm tall jar (and probably more).

That's a work in progress because the support directly attaches to the lid, which makes it rather weak, so a slightly larger may wedge it off. Also, probably 45° is pretty steep and one could improve the exposed surface area with a lower angle.
