A few words about the building .....

I leave the material to the customer's choice.
I've found that if I recommend PETG, for example, not everyone can print it out nicely. ABS does not hold on another bed.
The model is designed so that if you choose your favorite material it will print without any problems. I have already printed them from PETG, ABS, PLA, CPE.
Choose a material best for your printer and has beautiful layers.
I recommend a layer of 0.2 mm, just 20% fill. For tires 5%
But if your printers combine layers, take advantage of it. Alternatively, if you want a very detailed surface, print on a 0.1 mm layer.
The beauty in 3D models for printers is unique. Each model is different, as a different procedure can be used.
This is just modeling for me! Uniqueness. I also recommend that you color the models. Sand, putty, add use metal details. The model will be unique, and it will not be just a plastic toy.
