This post is for a custom 3D printed 1989 Jack Nicholson Joker bust at Diamond 1/2 scale bust size. I have a Deadpool from Diamond Select that I put side by side and did the same measurements. I'm just throwing this out there because Sideshow Legendary Scale is 1/2 too but are larger.

What you see in the vanilla color is liquid 3D resin, and the white, primered purple is Bambu PLA plastic filament. 

The Hot Toys Joker figure is just there to show scale and height. He's not included.

This weighs 1 pound and 6.5 ozs.

Any questions please ask.
