About this 3D model

A parametized OpenSCAD model of a vent or drain cap with an included screen on the end. Parameters include: + Throat (non-screened end) depth, height and opening + Mouth (screened end) depth, height and opening + Screen size and opening Note that it has only been run with the *mouth bigger than the throat.* If you need it the opposite way, you may need to tweak the model. Note also that this thing takes *quite a long time* to render in OpenSCAD (about 30 minutes on an i5 under Win7) and to slice (about an hour and a half with Skeinforge on Ubuntu). As posted, it has a 5 inch mouth and a 3.5 inch throat. All output dimensions are in millimeters.
