Based on very neet ZenziWerken's design https://www.thingiverse.com/thing:3025043.
I downsized it to A4 and added a licence free scheme to test cutting and engraving of thick wood.
EDIT 28/11/2018 :
removed extra useless objects from SVG file and changed cutting path color to green
EDIT 29/11/2018
created a greyscale version with cutting path in red with Trotec laser machine colour profile
