========= if you need to cut model into pieces feel free to dm me! I deliberately did not divide the model into pieces because different printer models and bed sizes suggest different separation. For example, my printer allows you to divide the model into 4 pieces of 27cm wide, since my bed is 300x300 mm, but if you don't have such a large bed, this may not suit you.
if you want split model by yourself i recommend to use meshmixer.size of model various from 55 cm to 50 cm.
A diameter of a circle is around 50cm, and 55cm if we measure including a triangle off-circle part.
purchase includes 3 variation of ornament.
