Would this spatula work? Only one i could find at walmart
Absolutely. May have to sand an edge on it though.
I got a nice dremel tool for that lol
Ok thanx man. Im at the register now lol
I know this is too late but I second @ThantiK Try to pry off by hand first though.
Lol ok
I have used those and they work well.
Personally I just use a putty knife and a spent utility knife blade. Just get a corner to lift with the blade, then get the rest of the model up with the putty knife.
I use this to lift a corner of the part and the spatula to do the rest. Works great but be sure to round the corners of your razor blade.
Even a coal chisel and a 5lb sledge hammer will work. It’s all about the technique and being gentle with the print and the surface.
Lol thanx guys ill see if i can make this work 
Tom Sanladerer used a wood chisel in one of his recent videos. The video on PEI restoration.
How good of a printing surface is pei?
Might be too delicate. I’d imagine it would bend or even snap.
