See through object, with fresnel effect.

Hello,

I am quite a newbie when it come to shaders. What I want to do is, that my hex based maptiles are see-through and only the edges are visible. My problem is now, that when I make my shader into a material and put that on my hex the hex is not see through.

My shader: shader-graph-fresnel hosted at ImgBB — ImgBB
Note:at PBR Master I set the shader to transparent
The tutorial I followed for the shader:

Thank you for your help

Edit: The model I am draging the material, created with the shader on, is a cylinder with six edges imported from blender. It doesn’t have any texture
