Hello, this is my first upload. I have a project to make a 3D model of my 1930s typewriter. It was made by a French industry named JAPY. 

This is the first part I have made; it is the top roller that controls the height of the paper. I used physical measurements, so the part is not 100% accurate, but I think it is enough to recognize the system. 

Feel free to ask if you have any questions/recommendations, and be kind, this is my first big project. 

Hope you like it!
