I tried to use my mmu2 for something of my own.
I have created those fellas, but multi material overgrew me.
So i decided i will paint them.
I am uploading 4 models.
3 of them (old ones) are a fit to one another.
the new one is bit more slick. its just a single stl but making a mirror duplicate will do the job. Also there is a STEP file, of the new concept. so you can create your own story.
The author hasn't provided the model origin yet.
