Parametric cylindrical jar with screw lid, side and bottom ventilation holes; size and holes tunable in OpenSCAD.

I based my design in another scad that generated chamfered jars with lid:

Added body and bottom holes and created the double_lid script to create the final radial structure of the different parts.
Many paramaters remain unbound on the script to give maximum flexibility.

Included base and inner .scad files to exemplify the parameters.
Sample small finished air filter included as stl.
