Another funnel, again...

My Vevor compressor came without hydraulic oil (has to be: ISO VG46 or AW 46) so I needed a funnel to fill it with oil. The funnels I had did not fit or fitted poorly. The funnel must have a spout with an offset wrt the center towards the fill opening. The ones I found on Thingiverse did not have a spout that will fit and go inside the fill opening. Thus I create one that allows an offset spout that will fit into the fill opening. You can customize all dimensions. My favourit is funnel4Vevor3.stl . Note that my computer uses metric dimensions.

CLEAN the funnel before using it !! You do not want plastic particles in the oil !!!!

All parameters:
- **$fn** the number of fragments to create a round shape like a cylinder or circle.
- **wallThickness** the thickness of the walls, in mm.
- **topDiameter** the diameter of the top section, in mm.
- **middleDiameter** the diameter of the middle section, in mm.
- **bottomDiameter** the diameter of the bottom and spout section, in mm.
