These are keychains of cars. They all are different common car models.
Currently the models include:
If there are any other car models that you would like me to create, then you can comment it, and I will try and create it. The size of these keychains are 40mm x 30mm x 5mm. There are no print settings that must be followed, but the settings I used were 0.2 mm layer height, 2 walls, and 15% infill. The print profile has these settings as well. Also the print profile has all of the models on it spread out onto different plates. If you only want to print one, you can either only print the plate you want or download just the model you want from the stl files. I hope you like the model, and happy printing.
