Turbofan aroma diffuser - Car vent mini Jet engine

Important: Using a heat-resistant material is critical for this project, especially for the clip that attaches to the vent. Beware of risk of clip deformation after parking under the sun, it may become loose over time (even with PETG). Temperature inside a car's dashboard can easily exceed 65C (150F) on a typical summer day.

Please note than plastic-to-plastic contact will often generate a bit of noise, but personally I don't even notice it when I'm cruising. 

If you already printed the V1 version, the only parts that have changed in geometry and that need to be reprinted are: ‘shaft’, ‘nacelle_top’, 'tip', and ‘fan_with_brims’. The default vent clip included, is now printed flat for increased strength.

This miniature jet engine easily attaches to your car's AC vent. As it spins, it releases the fragrance of the elements you place inside its inner container.

Among the things you can place inside here are some options:

• Freshly roasted coffee beans
• A cotton with a few drops of essential oils
• Aromatic plant leafs (lavender, rosemany, etc) - make sure they don't pass through the lid once it's closed

Utilization

1. Place the aromatic elements inside the recipient and screw the lid on top.
2. Screw the top cover
3. Place the fan - the side with extruded circle goes up 
4. Insert the shaft - press until it clicks or hits the bottom. Make sure it is well aligned.
5. Place the tip of the fan and screw the car vent clip on the rear part. In case the tip doesn't stay atttached try scaling it down slightly.

Important:

• Printing with a heat-resistant material (i.e, ABS / ASA)
• If the fan is too lose, which may happen depending on your tolerances try scaling it down slightly.
• If the vent clip doesn't work for your car, I have included a second design as well.

If that still doesn't work, please feel free to reach out to us in the comments.

• The fan may not spin at lower air conditioning settings, but a bit of WD40 on the shaft may help.
• As a general caution: Do not place any ingredient that can be bad for breathing and do not manipulate while driving.

Print Settings:

• 0.16mm layer height for the fan, the rest can be done at 0.2
• No supports
• Clean the fan from any burr or imperfections after print to improve the spin.
