Yet Another Parametric Vented Funnel

I started editing Peter H's “BETTER VENTILATED FUNNEL - PARAMETRIC” so the parameters could be edited without creating an OnShape account, only to discover that they still won't let you download an STL without an account. I decided to keep editing, and tweaked a few of the parameters to better fit a funnel I needed, so by the time I was done it was different enough that I felt it would be worth sharing. As with Peter's model, you will still need to create an account (you can do so for free) in order to make changes and download an STL.You can view the source model here, or via the (way too tiny) “Link to the source model files” link just below the STL file on the download page here.Main differences from Peter's original:Parameters are now stored as “configurations variables” so they are a bit more user friendly for edits.The handle is now optional, and has additional parametric configurations including where it's located, and its thickness.Funnel height is configurable via length (for the tube) and angle (for the funnel mouth).Vent size now has minimum diameter so you can create very-small outlets without the vent interfering.The example stl file provided is for a small funnel with my default settings of an 80mm diameter opening, 10mm outlet, and a 1.5 wall thickness. These are arbitrary, and I encourage you to make sure to set the wall thickness to a multiple of your extrusion width (for strength, I print mine with 1.8mm walls for a 0.6mm extrusion width from my 0.4mm nozzle).
