3D printed. Very close to the original size and fit.

Does not include the metal insert. You will have to insert your original metal neck into the knob. If you do not have the metal insert this will not work for you.

I personally designed this and 3D printed to be as close to the original as possible.

I have been working on typewriters for over 7 years and it can be frustrating to see the original knobs on these beautiful machines broken or cracked. This is a great replacement to the original and is very strong and durable!
