I am working on a project that involves creating a spherical dodecahedra using 12 pentagons glued to a 3 inch plastic sphere. I need to be able to create a 3D printable part (which will be printed 12 times) and I am having trouble figuring out how to make a solid part out of the geometry that I have so far. I am pretty new to 3D modeling in general so this may end up being something very easy for someone with a bit more knowledge of SketchUp.
I have created 2 spherical dodecahedra. One of them is three inch and the other is 3.25 inch. I then joined all vertices from the smaller dodecahedra to the larger. The part that I am struggling with is creating a solid part out of just one of the panels. I want to be able to increase the size of the interior sphere as well as the depth of the panel incase I end up using a smaller/larger plastic sphere or if I decide to make a thicker/thiner shell.
Any help would be greatly appreciated! Hopefully what I am looking for makes sense.
I have attached the file that I am currently working from.
