Step 2: Splicing

put the STL file into your splicing software (I use Cura) then change the supports to everywhere and export it as a gcode for 3D printing. then print the gcode using your printer. after about 1 hour and 30 min the print should be done, then you can paint them. now they are ready to save one (Micro) galaxy at a time.
