The whole card can be 3D-printed in one go without any extra parts except for some wire. The card can be printed without support, and the print time is about 2 hours with 30 percent infill and a 0.1mm layer height. The card can be printed using regular PLA. The whole thing is designed to snap fit together so there's no glue necessary. I did many test prints of different parts of the model until I got some consistent results. It is possible that depending on which printer you use, the result may vary. You can always let me know in the comments which parts work for you and which don't, so I can create a second version of the model. I added all the parts separately to make it easy for people who just want to print the catapult without giving the card as a present. I also created some instructions to add to the experience of building a model kit. The pdf file is available in the file section.
