JDM style wheel lug nut/bolt cover type3

Do you like JDM style car modification? 
If so, you might have noticed that those modified JDM car's wheels are often decorated by its unique long and colorful wheel nuts.
However, if you drive an European car, it might be difficult to enjoy it because many European car manufactures choose wheel bolts instead of lug nuts.

With this wheel bolt/nut cap, you can add some JDM touch on your wheels instantly.
It's designed for most common 17mm hex head wheel bolts.
Of course, it would fit to lug nuts as well, as long as it's 17mm hex shape.

I made different 3 types for your preference. 
2nd picture shows how it looks when it's attached (type2, 45mm)
3rd picture shows all 3 types. Each one is listed separately.

1 zip file contains 5 different length: 42, 45, 48, 51, 54mm.
So please choose the one suits your taste.

3D printing settings recommendation

Material
It depends on your purpose. 
When you want to keep them on the car continuously, strongly recommend to use an engineering material such as ASA, PA...that withstand the environment.
If you use them for just an event or a photo shooting session, then you may choose a fancy looking one such as a metallic look PLA even though it will probably not last that long.

Scale
To achieve the best fit, you might need to scale the model in your slicer.
Fitment depends on your wheel bolts, 3D printing condition and material you use.
Therefore, I recommend to test print 1 piece first, then check the fitment, adjust the scale, if necessary.
