This is a replacement cover for a pen pad.  It's the exact dimensions of the original just slightly thicker to be sturdier.  

I unrolled the wire from the old notepad cover and onto the new one but you could also snip the top of each circle and snap it onto the pad and it holds well doing it that way too.

It takes up the entire length of my build plate so I had to make some slight adjustments to my slicer settings to get it to slice and fit on the build plate.

I would love to see your makes and any comments that I can improve on!
