A simple tool to help removing your skirts, purge lines and some small prints from a PEI bed without touching it with your fingers (Fingers leave oil on the print surface => prints don't stick as well). While it's nearly impossible to completely prevent dirtying of the PEI surface, not touching it as much will delay the need to clean it. If used correctly the scraper won't scratch or mar the surface unlike metal paint spreaders/scrapers.

I recommend at least 0.16 layer heights for the bottom to get a nice edge. 

Happy printing!
