Print at 0% infill. 1-2 layers for the wall thickness, allows light to light it up. I find transparent Orange at .08 layer height at 35 mm/s did the best for me (31 hours to print). The right eye and left eye might need to be adjusted or shrunk down to fit the sockets.
You can print his hands without support if you keep layer height low (.08 for me), and have it an an angle so the base of his arm is the flat part against the bed. its a pretty diagonal angle but I was able to pull it off. If you can't, try with supports.
The stone piece is rather big, I'd measure to what you feel comfortable with. I included it cut into 4 pieces or as 1 big piece. I printed mine at 5% infill and it was 1.75lbs of plastic. You can shrink the height to greatly reduce the plastic usage. I needed it the height it is to hold a light bulb socket to allow it to light up. Depending on your light source, it can vary.
