The wire that support the Moon and the stars have been embedded in the printing layers.
First prepare the files in the slicer and then insert a pause at half height (for example 30 layers, pause after 15 layers).
When the printing stops, take a piece of wire and, using a piece of PLA film, glue it into place with cyanoacrylate glue.
Cut any piece of PLA used to fix the wire and make sure that the wire that comes out of the print is perfectly adherent to the last printed layer. (I used paper tape to keep it taut at the bottom). At this point resume printing.
Print all the smaller pieces first and make sure their height is half as high as you will print the crescent moon.
When you print this, take care of the position on the plate, so that when you stop the printing you can place the stars and the hook made previously next to it, without them hitting parts of the printer while the plate moves.
Again I held everything in place with paper tape.
The author marked this model as their own original creation.
