We noticed that some of the shells were stuck/fused therefore it could not be separated.
In addition to solving this problem we increased the smoothness/resolution of the file.
The scale is 1/6 (12 inches recommended) but you can print it for any size even 1:1 for Iron Man armors.
Resin 3D printing is recommended for smaller scales and if you want to print it for 6th scale or below, you would need to reinforce the hings with metal wires.
