Hi Guys,

I have my Creality K1 max printer for a while now and printed some basic stuf.
Now i want to take this up to the next level, en begin to print helmets.. I bought an Iron man STL and like most helmets this comes in parts.

Can someone walk me true this?
I know how to measure my had so it would fit me. But for example, how do i know how big all the parts needs to be so it will (still) fit in the other parts?

I hope someone can help/walk me treu this. I wachtend a lot of youtube movies, but non of them explains this part.
