None. Shakespeare did not "model his characters" on individuals. Since he borrowed most of his plots, the characters came with them. Shakespeare broadened the characters in the stories he found but rarely invented any. Many of his characters are stock characters or similar to them. (Maria in Twelfth Night, for example, is a soubrette)
Falstaff if perhaps an exception. He appears to be entirely Shakespeare's character, and in making him Shakespeare drew no doubt on many real knights of his acquaintance.
If Shakespeare had even heard of an artist who wandered from job to job around France and Italy a century earlier, his plays show no sign of such a character.
Leonardo may be the model for Platon.
He impacted my life allot he is my role model.
He did build a working model of one.
Like most figures who achieved the status that Leonardo De Vinci achieved, he did have a role model in his apprentice Andrea di Cione. Cione was one of the most celebrated artists in his day and he encouraged De Vinci to practice literature, history, and philosophy as well as art.
It is said he made a couple of tests, but no successful flights are recorded.
At least two horse sculptures, the model and full sized clay cast model for Gran Cavallo.

Salai was a young apprentice and companion to Leonardo da Vinci. Their relationship was complex, with Salai serving as a model for some of Leonardo's paintings and also assisting him in his work. There are suggestions that their relationship may have been romantic in nature, but the exact nature of their bond remains a topic of debate among historians.
Click link below and see his drawing + one modern model! Note that the 'helicopter' was never executed!
The painting is a portrait of the wife of a Florentine merchant. Her name was Lisa Gherardini.
A device used to draw parabolas. There are sketches by Leonardo da Vinci of a device that was supposed to do just that, but I can't find evidence of a working model.
I think he built it with the help of his uncle. It was a model made perhaps by looking at maple seeds falling. Look at the link below:
