Giá đỡ cuộn filament cho tủ Ikea Billy

I store my filament spools in a Billy cabinet from Ikea. Instead of the regular shelves, I use rods (solid bar or tubes with a 12 mm outer diameter) made of stainless steel. These rods are 750 mm long. The spools are held in place with the holders shown here. These holders are attached in the Billy holes using 3.3 mm dowel pins (length 15.8 mm).
