About this 3D model

I designed this spool for my Olivetti Lettera 32 typewriter by measuring the typewriter. I didn't have an old spool to work with. It came out great. Going to add a ribbon soon, and use an inkpad to ink the ribbon. I don't know if it will work on other typewriters. If you tell me the dimensions of your typewriter, I'll design a spool for you if I have the time.
