You can also print all the parts seperatly so you don't have to remove any card material. The whole car can be assembled without the need for any glue. The print time for gift card 1 (the one with the most parts) is about 4 hours. The print time for gift card 2 (the one with the wheels) is about 2 hours. I decided to print them with 100 percent infill because there wasn't that much of a difference with 25 percent infill, the print time was about the same. Another reason for 100 percent infill is that the spring is being printed better. I tried to arrange all the parts on the card so that it is possible to print the 2 cards in 2 different collors
