I modeled this in Onshape for one of my granddaughters, who is a big fan of the show. To be accurate to the show, you'll need three colors: yellow, black and white.
I have included images of the build plate so you can see the part orientation and supports I used. Notice that a spare surface may appear over the “Bill Cipher Iris” stl file on your slicing software. It will disappear when slicing and printing.
You'll need to clone a copy of the arm and leg. If you're picky about symmetry (like me), you'll need to mirror the cloned arm in your slicing software so that the hands look right. The leg clone does not need to be mirrored for symmetry.
If you're impatient (like me) you can pause the build of the black parts, after the shorter parts are completed, to remove them for final prep. The build may then be resumed to finish the arms and hat.
The author marked this model as their own original creation.
