The 3D Nail Project

I am working on creating a set of very long nail. In the 1st try, I printed the nails by the 3D printer but it didn’t work. In the set of five nails, there was only 1 nail came out decently as you can see in the picture. It’s length is 6 inches. In the 2nd try, I created the nail longer and printed them with the resin material instead. However, it was also failed because the nails were too thin. They broke into two pieces as you can see in picture.  The length of the 2nd try is 9 inches. I am now trying to reprint the nails again after made them much thicker.
