Supports needed from the print bed for the base part (upside down printed)
Using a brim could help if you face problems with adhesion.

Textured sheet recommend:
If you use a textured sheet too, let it cool down completely after the print and wait for the part gets loose by itself. Do not pull on it to avoid ripping off the letters!
In my case it takes 45-90 minutes after the print has ended and the part just lays loose on the print bed.
Do not touch the print bed and clean it with Isopropanol alcohol before printing.
