Compact Diesel Fuel/Additive Funnel (with .f3d)

❤ If you like this model, drop a like to support my 3D printing addiction (er... I mean hobby)!

A compact, light, and quick-to-print diesel funnel, suitable for additives and diesel fuel itself. The funnel opens a standard UK misfuel protection flap on diesel cars, same as the diesel nozzle at a forecourt.

The funnel also features an air backflow channel, which reduces bubbling and diesel splashes. This is exceptionally important in compact funnels when refueling from UN jerry cans, although given the size of this funnel, the overall experience filling the tank with it is slow.

Printing

This part was designed to print in one piece in most 3D printers. However, you may trim the stem to length in your slicer as needed. For this purpose, I've included a _longstem version.

PLA warps in a hot car, so I recommend using PETG. Remember to remove plastic strings which may clog your diesel filter.

Thick walls enable fast printing with tall layers, retaining great water-tightness nevertheless.

Safety

Effort was taken to design this funnel to reduce splashing and other hazards. Nevertheless, when you use funnels like these, be responsible. They are inherently less safe than your forecourt nozzles.

The essentials:

• Review your country and region's rules for fuel spills.

• Diesel spills are slippery and pose a hazard to cyclists, motorcyclists, and pedestrians. Most regions have a phone number you can call for clean-up.

• Don't decant fuel near water bodies and storm drains to avoid water pollution, which may be a serious offense in some countries.

• Likewise, don't decant in the rain.

• Diesel ignites easily in small amounts, such as droplets held in FDM-printed micropores.

• Don't use with gasoline. Gasoline ignites easily, can damage some plastics such as PLA, and remember that this funnel bypasses the car's misfuel protection.

• Putting incorrect fuel or additives in your car will cause damage.

• 3D prints develop cracks along layer lines. Inspect the funnel before use.

Use responsibly: don't pollute the environment, injure yourself, or damage your car.

If you choose to sell or exploit this part commercially or distribute physical prints to users, remember that this may involve additional legal duties and safeguarding.
