My design made for Batman Vs Superman contest. Superman fighting the bat crashing into te wall.
The best way to print it is upside down. Be careful with the support placement, superman arms are the delicate ones but with 5 - 10 supports will be enough.
Build supports around Superman shoulders, cape and head
Batman arms and hand.
Infill %15 for a stronger sculpture.
2 Outline shells and 2 bottom solid layers should work.
You can use PLA material and apply acetone to make it look like rock texture. In the back part has two holes to attach it to the wall nails.
