Use auto tree supports. There is a .3mf that has the models painted if you plan on doing multicolor.

If you need a commercial license to sell 3D prints of this design, make sure to join my Things membership. You’ll make back the cost in just one or two sales, and I of course would be forever grateful for your support. 🤗 I hope you enjoy the file and please connect with me somewhere and tell me what you think. I’d honestly love to hear from you.
