I designed and 3d printed this tool to help me with shaping dome and sphere shaped parts when building 3d metal models like those from Metal Earth, Piececool, MU, Tenyo, Picture Kingdom, etc. I designed this tool after designing the Cone Shaping tool set. Since I already had something to form cylinder shapes, I decided to combine the tools into one to save space. I have been building 3d meta models for over 3 years now. You can find my build and review videos on my YouTube channel animateorange. These tools are very useful for shaping dome shapes, such as propellor cones, curved parts such as shoulder and spacecraft/aircraft fuselage and similar items. The center section can also be used to shape shallow domes.
The sizes of the domes from largest to smallest are as follows:
