-The lighthouse has four parts, which can be printed as one piece, by using the merge unction of cura. - If you have a two extruder 3D-Printer you can also print it in two colors - By printing it as one piece, you have to build support material for the balcony. - I have printed it in two pieces: 1. Merging STL-File one and two by using red and white. 2. Merging STL-File three and four by using transparency for the light and white for the balcony and the top Then I gum both pieces together
