03/2026 - added customizable version

I needed rise up shelf about 20mm to be able higher books inside, but I did not want to drill new holes for pins. So I made extenders for 5mm pins. 

You can find two versions with key and without. I have shelf with key which holde board in place. But there is also option without key if you need.

If you need bigger extenders let me know I can add it.
