Funnel with air duct + anti-spill edge + removable S-extension

I needed a funnel to pour some gasoline in my motorcycle's tank, so I designed and printed one myself. As it was very important for me not to spill any gasoline on the tank paint, it has a bunch of features:

• integrated air duct to allow trapped air to exit the funnel without disturbing fuel flow;
• anti-spill edge;
• removable S-shaped extension to be able to reach into car/morotcycle tanks,
• sized to match the standardized gasoline nozzle.

Dimensions (see pics):

• Funnel:
  • 140mm top diameter
  • 20mm bottom diameter
  • 100mm height
  • 50° wall slope
• Extension:
  • 20mm diameter
  • 200mm length
  • 45° slope

I printed it in PETG, which is resistent against gasoline. No supports needed (maybe just a brim for better bed adhesion for the the S-extension).

I'm not gonna ask for a coffee, but please make sure you give me a like if you find this model useful.
