Small insert board for Ikea Billy shelf

I need only one ikea billy board for my shelf. So why not print in PLA Wood? 
This should fit 100% alls measurements were taken from the original one.

I added a pre sliced file for my XL. I needed to cut 1,5mm on each side to make it Fit, but this is no problem for me. I also changed the infill and Topand bottom layer setttings to make it more interesting.
