Parametric hydroponic glass lid (for parametric-net-pot.scad - by leemes)

A somewhat parametric hydroponic glass lid inspired by leemes parametric net pot (OpenSCAD) design.

You can find leemes model https://www.thingiverse.com/thing:790339

I declare this model as only “somewhat parametric” because I couldn't figure out the math how to calculate the optimal top thickness parameter so that it would be an optimal fit for any net pot made with leemes OpenSCAD model.

You will have to play with this value manually and look at the sketch in the Revolution to see what fits.

2.4mm seems to fit nicely in the example shown in the screenshot below.

In case it's not obvious you will need to import your own net pot STL file and transform it (move it down) to see what top thickness fits nicely. If someone can help me with the math involved to calculate the top thickness feel free to remix my model or contact me in the comments and I will try to update the model. I don't understand OpenSCAD code well enough to get this done on my own.
