Spiderman Helmet (Iron Spider)

This is Spiderman (Iron spider) helmet that can be worn as cosplay, with magnets (5-6mm depending sizing) to connect the halves.
The helmet itself is sliced in four parts (2 front parts and 2 back parts) to allow easy printing in common printers, and then you'll need to print as well the Eyes and the mesh that goes behind them.

You may need to adjust the size to your own head - I included a “Slice Experiment” which prints only a few layers of the full helmet so that you can check if it fits your head (either on the forehead or below the nose). Adjust the size of the slice till you get it right (leave some extra space for confort), and then slice each of the helmet parts with the same size settings.
