Custom made 3d printed mandalorian helmet, from scratch

I am 15 years old and love to make helmets for fun as a hobby. I have made this custom mandalorian helmet but I don't have any room for it, therefore wanting to sell it. It's in great condition appart from one layer line at the back where the top and bottom half separate. It's not verry noticeable. I printed, wood filled, sanded untill really smooth, primed it with spray primer, sanded again, black gloss spray paint, clear gloss and repeated the spraying paint. Then applied graphite powder all over to give the helmet the mandalorian Beskar look. All together it took up to 35 hours to make including all steps. Please not this helmet is complete apart from the visor . THIS HELMET DOES NOT HAVE A VISOR. I am really proud of what I have made and hope it goes to a star wars fan like me! If you have any questions on size, material, what I did or anything else, please feel free to message and Ile be happy to answer! I will also be happy to negotiate price!
