Leon McCarthy has a colorful new prosthetic hand. his Dad made the hand from the new 3-D printer at Leon’s school. With his new hand he can grab more than one object. His Dad only spent $10.00 on parts for the new hand. Leon’s science teacher helped out on making the hand.
If I had a 3-D printer, I would print Nerf guns. I would make at least a hundred Nerf guns. My favorite thing to do with Nerf guns is target practice. I also like to have Nerf gun fights with my friends. The reason I would make Nerf guns is they are expensive to buy.
