Scrapper

A universal tool for removing prints from the bed without a chance to damage the surface. More likely you will break the scrapper than scratch the bed. 

Context

1. PEI sheet is a very good surface for printing. 
2. You need to wash it with warm soap water or clean it with isopropil alcohol to get the best adhesion. 
3. If you touch the bed with your fingers, get back to point 2.
4. Metal scrapper scratches the PEI surface.
5. I am lazy.

Solution

Print a scrapper to use instead of a metal one. It does not scratch the surface, you have more chances to not touch the PEI sheet with your hands and make yourself to clean it again.

One model is having 3 edges with 45 degrees angle - when you have one edge damaged you have a couple more. 

Another model has 3 different edges - 30, 45 and 60 degrees. 30 and 45 are good for removing nozzle flush line and skirts. 60 is good for removing small parts from the printbed and for removing a sticker from a fridge.  

Side bonus

It is an unexpectedly great disposal tool to clean a glass stove. Or remove stickers. You name it.

Backstory

First I have modeled something looking close to the scrapper included to the Ender 3 set. Then understood that I don't have to follow the same rules, what allowed me to get 3 times more edges.
