*Without permission.
Also has nothing to do with not allowing remixes to be exclusive. If a model is remixed, that doesn’t make the original a remix therefor doesn’t restrict it’s eligibility to be exclusive.
Any remixes would (I imagine) need to remain only on Makerworld though, and as such should also be uploaded with standard licenses. Nothing prevents this, the users simply need permission from the original creator with the stipulation that any remix can only be uploaded to Makerworld for as long as the original remains exclusive. A remix obviously can’t be set to exclusive though.
@Talon They’ve said no remixes but AFAIK only in a reply post here on the forums. Also Kit’s correct in that it is 100 prints (total for your whole account btw) and not 100 downloads.
