1 minute
This is a simple pattern.
You type in a name
Duplicate the name
Set the original to zero.
1 minute
Take the duplicate and use the offsetter app to make an offset
1 minute
combine the offset and set it to full depth
1 minute
slide the offset behind the original
and “select all”
the center horizontal and vertical.
1 minute
add support tabs to the outside edge.
Since you will be completely carving away around the letters,
add little support tabs to hold the work until complete.
I used rectangles 1/4 × 1/4 inch set to .001 depth cut.
