Excellent overview of the linear extrude function, thank you.

Thank you for this very helpful information!
How to use "spacing" for each letter?
E.g. as I want to use a hand drawing font I only need the first letter to be adjusted because the other letters are touching each other.
At the end I will 3D print the text.
