I did a quick google search and found a puzzle piece already in .svg format.
I imported it into Easel, removed the bottom cutout, and resized it to my wood dimensions.
I then added my text and made 2 copies.
The first copy was for the text to be carved with a 60° V-Bit.
The second copy was to cut out the puzzle shape using a 1/8" 2 flute bit.
