These are customizable braille signs. Every part contains one letter, or a number. The letters can be ordered to a word, and be attached to an item, to show, what's inside or what it is. You can attach the word directly to the item, or renameable with the mount. You can easily slide old letters out of the mount, and slide new letters. These can be used for example for boxes, with changing functions. The letter parts contain the letters in braille font are looking out, so you can easily feel them. The letters are also written in the normal font on the part, but looking in, so the person, who feels the letter doesn't get confused. At the bottom of the part is a small border, which indicates the bottom of the letter, to help a person to orientate the item in the right direction, and read the letters the right way. The parts are so designed, that through the size there shouldn't be any warping, and no support material is needed. This makes the parts easy to print. I couldn't enter a picture of every file, but it should show, how it looks like Unfortunately, I don't have a 3D printer available at the moment, that's why I can't print the parts.
