Hello 

So i started a project of making a hotas for my pc and found this model of a grip i like i imported it into solidworks dissolved it and then attempted the heal all operation but it took ages to do hardly anything.

I want to be able to modify and eventually make a shell out of this model for 3d printing but i cannot work with it at all as i cant figure out how to fix it.

So can you please help me so i can play elite dangerous already?
