Pose a 3D model, then flatten it onto the board
Open a Minecraft skin or a glTF model, turn it to the angle you want and pose its limbs. Enter freezes it onto the board as an image. Shift+Enter splits it into parts hinged at the joints, so the arms still swing when you pick it up.
J turns the rig into a ragdoll. Back on the board, Alt and the scroll wheel still turn it in 3D.
