This is a remix. The demogorgon is best printed in individual parts, but of course it can also be printed as a whole. 
The problem with the whole Demogorgon was the support that caused it to wrap around the fingers, which unfortunately led to them breaking off when the support was carefully removed.

Connecting pieces are included for all individual parts. Support amplifiers have also been included to ensure secure pressure.

The tendrils on the base are made of rolled aluminum foil which are then simply painted black.

(I will add the tendrils to the base later so that the aluminum foil can be left off)
The clear varnish at the end gives the whole thing the wet look as you know it from a demogorgon from stranger things. 
The saliva on the snout is made of glue that I ran from one mouth flap to the other mouth flap to connect them for a more authentic look.
