The zip file contains all the uppercase and lowercase letters written with the UNICO font individually saved each as .stl file plus a .stl file containing the entire alphabet
The Alphabet.stl file, containing the entire alphabet, was printed with an Ender3, it can happen that, for the Delta printers, the image is too big, in this case the dimensions can be scaled. Created with Fusion 360 Extrude 4 mm
Have fun and good 3D printing!!!!
