As with all of my countryball models the parts of Denmarkball can be printed separately on a single color FDM printer. 

All parts are designed to be printed without supports and they can be assembled with snap fit joints. However this means that the tolerances are pretty tight and any elephant foot or stringing could interfere with the connections. I've tested the models on my Ultimaker 2 and Prusa MK3S printers.

Secret tip: You can print it in the colors of Sweden or Finland as well.
