Spoiler warning: Below I am talking about some generic enemies that may be encountered in the campaign. If you don't want to know about any of those, stop reading.
I have been looking for 3D printable minis (STL files) for all enemies (and some allies) for use in the campaign. In particular the more Ancient Greek ones like Gygans and Blemmys are rather hard or impossible to find. I have found models for Blemmys, but didn't like how they looked. So for these models I have decided to use minis of regular Giants instead. Not an exact fit, but close enough, and reusable in other campaigns. There is a bit of a problem with size though. Almost all Giant minis are placed on 100mm bases, which would be equal to a gargantuan creature in DnD (please correct me if I am wrong). Even worse: Gygans and Gigantes are large creatures and would fit on 50mm bases in DnD. (Can we still call these giants? They aren't that big.) Of course I can scale the Giant minis to 50% of their size when printing them, but part of what makes a Giant mini a cool mini IMHO is that they are posed having regular sized things on their persons, like holding a regular sized human body in their hand, having a full cow dangling from their belt, carrying a cage with a human in it with them, etc. By scaling these minis these things would become ludicrously small, So I would rather not scale them down.
Any advise on how to deal with this? Other DM's that use minis: How did you do this? What did you use for Gygans and Blemmys?
