This is an improved version of Tomaae's parametric funnel with additional parameters and the ability to enable/disable “optional” features. It also includes support for a tapered tube section. The table below contains a complete list of parameters.

Due to the parametric nature of this design and the heavily customized print settings I used, an STL was not included. I encourage users to use export their own STL from OpenSCAD and load it into my 3MF file. I used a 0.8mm nozzle to improve print speed.

2022-07-24 Update: add ridge thickness parameter to improve vase mode printing quality. Update sample 3mf to support vase mode “out of the box”.

Note: I strongly recommend printing this in PETG due to its excellent chemical resistance.
