Airplane Prop Car Accessory
Intro: Airplane Prop Car Accessory
Hi All,
A friend of mine, who is a pilot, was getting married, so me and my brother-in-laws thought up this project as a way to spruce up the newlyweds' drive-away car.
This airplane prop is a fully 3D printed assembly, except for two screws and 10 air-soft bb's for the ball bearing. Once assembled and mounted, the propeller spins via wind power as you drive. I've taken it up to 55 mph, and it works swell.
Before we get started, I would like to give a shout out to Brian Bartlow, a.k.a. TheRooster, on Thingiverse. I integrated his 608 ball bearing into the axle and front-plate of my Airplane Prop to help smooth the motion a bit. So many thanks to him and his excellent work.
STEP 1: What You'll Need
Tools Needed:
- 3D Printer with minimum build volume of 7.5 in x 7.5 in x 4.5 in (190mm x190mm x115mm)
Materials Needed:
- Plastic Printer Filament (I used PLA)
- 8x 6mm BB's
- 2x Small Wood Screws
STEP 2: Print the Parts
Download the STL's below and configure your gcode with your favorite CAM software. I used the following specs when printing these parts:
Layer Height: 0.15mm
Shells: 3
Infill: 35%
The only parts that should need additional support material are the Prop, Prop Blade, and the Prop Axle.
You will need to print the following number of parts:
1x Prop
2x Prop Blade
4x Blade Pin
1x Prop Tip
1x Prop Axle
1x Prop Frontplate
1x Prop Backplate
2x Plate PIn
2x Angle Bracket
2x Washer
STEP 3: Assemble the Prop
Follow the Instructional Video above.
All the pin connections are press-fit. You could add some C-clips to further secure the Plate Pins if you wanted; however, the pins fit tightly enough that C-clip really aren't necessary.
After fitting the Angle Brackets onto the spokes on the sides of the Frontplate, use a lighter to slightly melt the ends of the spokes. When the plastic becomes malleable, gently use a hammer to flatten the end of the spokes to prevent the Angle Brackets from coming off.
You will notice there are 6 screw guide-holes on each side of the Backplate. These allow you to change the degree to which the Prop is angled from the Backplate.
STEP 4: Time to Fly!
Alright, almost done! You are now ready to attach your fully assembled Airplane Prop Car Accessory to your car.
I used several Zip-ties looped through the holes on the Backplate, through my car's grill and under the hood to secure the Prop Assembly to my Toyota. Two loops of Zip-ties was enough to effectively constrain the Prop.
After ensuring the assembly is firmly fixed to your car, take a drive!
Thanks for reading this post, and enjoy your flight!

Regulation 53 Road Vehicles (Construction and Use) Regulations 1986 states: "No mascot, emblem or other ornamental object shall be carried by a motor vehicle first used on or after 1 October 1937 in any position where it is likely to strike any person with whom the vehicle may collide unless the mascot is not liable to cause injury to such person by reason of any projection theron."
Section 40A Road Traffic Act 1988 as amended by the Road Traffic Act 1991 states: "a person is guilty of an offence if he uses, or causes or permits another to use, a motor vehicle.... on a road when.... the condition of the vehicle..., or of its accessories or equipment.... is such that the use of the motor vehicle.... involves a danger of injury to any person."
I suspect that your propeller would be in breach of both of these regulations.
In any case, most modern cars have rounded, sloped fronts to minimize the damage to pedestrians should they be involved in an accident. This device does the opposite IMHO. You would also be liable to pay damages in court.

It talks about "forgiving geometries"

I was thinking that if this prop ornament becomes a legal issue, it could be mounted in the back and call it a push-prop.
