I just try some things out with Fusion 360, and this is what came around ;-)
The Idea is, that you can change the colour of the Border/Outlines at a specific Layerhight.
As long as I have no Printer owned, i can´t test it by myself so...
Please let me know if there are Issues...
I cleaned it up a little bit and increased the size of the hole
I Increased the size of the Border for better Border Stability
I forget, the the Size is not correct, i printed it with round 38% of original Size
20x52 mm works fine for me
I switched the Outline for Bold Text...
Works Much better for me :-)
Just print and have fun ^^
