Filament type recycling symbol watermark

[tonyalpskog]

After a lot of printing it's hard to know which filament type an old part was printed with. Knowing this for sure will help me solving some long term issues that might have occurred.

I'd like to be able to add a filament type "watermark" on a part before printing it. Preferably something that is more of a standard like these: https://www.acmeplastics.com/content/your-guide-to-plastic-recycling-symbols/ Even though most used filament will be of class 7, the actual name can be used instead of "OTHER" Like "PLA", "PETG", "ASA" or "ABS"

• Possibility to select protruding or indented watermark
• Adjust size of the watermark
• Finally choose where to place the watermark

This can also be a great feature if there is a possibility for some countries or locations to do actual recycling of filament plastics.
