Stack puzzle may seem simple at first glance, but don't get tricked. The goal is to find the stacking order of the elements that will allow you to use ALL pins to fill ALL the blank spaces in the elements.

This model can be printed on FDM printers from PLA, PETG and any other materials. Standard quality (or super quality). Layer height 0.2 mm or less. Nozzle 0.4 mm or less. Any filling. In the photo, the model is made of PLA (yellow and blue). If you are printing with draft quality and/or a nozzle greater than 0.4 mm, then first make one element and one pin and check their docking. If necessary, adjust the scale of the pins. The puzzle can also be made in one color.
