Tips for miniature design with printing in mind?

Hi team,
I wanted to ask the folks here who have had minis designed for their games, did you have those designed with printing in mind, or did you have the designs modified after-the-fact to make them printable?
My manufacturer will work with me to make cuts and come up with a way to do multi-print and glue to build the miniatures out. There is a cost to this, so I was wondering how folks approached this aspect of their game design.

Thank you for everything!
