I was looking for a London underground sign but was not able to find any. I designed this sign with the King's Cross stop because its one of the most famous stations (hint hint, Harry Potter).
Uploaded is the Fusion360 and STL files in case anyone wants to change the name or remix it in their own way.
I have not had the chance to print it since I am studying abroad and do not have my printer with me.
If there are any problems printing I can try to sort them out for you.
