Success! My termagant sculpts have been printed, and they're delightful! I still need to sculpt some weapons for them, but they work with the plastic gaunt weapons as a stop-gap.
This was quite a learning experience, and I hadn't quite appreciated just how...spindly they would be. On the plus side, Elegoo ABS-Like 2.0 is very durable and they don't feel like they're going to break. In hindsight I'll not add quite so many tiny bits in future as they're just so small that they get lost.
