I use the gridfinity bottles to store some spices, and although a teaspoon just fits into the opening, I found myself wanting a funnel cap to make refilling as easy as it can be.

This is a simple combination of two models, to make a funnel cap that fits into the gridfinity bottle. The funnel model uses PET cap, while the bottle uses milk cap. This remix just fuses these two STLs together. Result is a milk cap size funnel cap. There's no additional modeling from my part, other than import, move, rotate and cut, to align the two .stl files in OpenSCAD into one new STL. All actual work is done by the creators of original models:
