Ahlgrens Bilar (Bilar = Cars) are a big thing in Sweden (number 1 selling car of all time, true fact.) When my Ahlgrens USB keyring broke, it left a delicious car-shaped void in my life, until 3D printing came along! My keys are saved!
Sometimes extruders have a hard time finishing the top of the car, so you may need to use your printers 'cooling' function. Or print loads of them.
