Support Pins for Ikea BILLY bookshelf

I got an Ikea BILLY bookshelf from a friend but he told me that he could not find the supporting pins for the shelf board (should be part number: 131372).

So I made these parts with some quick dimensioning. They fit quite nicely and have been supporting the shelf boards for more then one year without significant creep. 

Print the part upside-down (flat side down) and 100% infill.

Disclaimer: Just being cautious, I do not recommend using these parts for long term.
