Ciao,

I reupload my files. These are components, and I have marked the quantity at the end of each file. Also, I need regular materials in black and white, if black is not available, all white materials are also acceptable. The course professors are Roberto Bianchi and Francesco Romeo. 

Because after I converted the file format, my software was unable to measure the size in STL format, so I didn't know if the size was correct, so I simply marked the size of a part. If there are any errors, please let me know and I will upload again. Thank you.

Sincerely,
