Parametric Customizable Fruit Fly Trap (Small Jar)

This is a remix of ridercz's Parametric Customizable Fruit Fly Trap. I have a set of small canning jars which I would like to fit with this lid.

Please note, both this and the original have a gotcha in the parameters. The `lid_inner_diameter` (measured in millimeters) is not the final diameter of the part, for that you need to add `lid_inner_diameter + ( 2 * wall_thickness )`. This wasn't obvious the first time I printed and the final part was too large. Also, this remix cuts the wall thickness in half compared to the original, so this isn't as large of an issue.

Changes:
- Clean up the model if a lip around the edge isn't desired.
- If the inner height of the lid is specified as 0, the lip is not modeled (fixing a rendering issue)
- Print faster, will less material, and with a cleaner print of the cone.
- Wall thickness has been reduced by 50% from 1.6 to 0.8.
- Printing at 0.16 resolution with a 0.4 nozzle this results in a wall that is 4 passes thick (2 i
