Hi Michael and Olga,

> I guess it sounded like Olga had done some other steps to the sphere and cone and was having a problem with booleaning after those steps?

That's the bit I don't get, if you do a offset/shell at 1.5-2mm with this piece the main walls of the triangle piece would engulf the offset of the
sphere and cone so the offset of those features wouldn't be necessary, or I am missing something here ?
