Filament spool holder for Ikea SKADIS

I HAVE NEW AND MUCH BATTER VARIANT OF THE HOLDER. PLEASE FOLLOW THE LINK.

I have tried few different spool holder solutions for Skadis but I wasn't happy, I needed something simple and decided to make my own. I have 76 cm and 36 cm boards mounted next to each other so I needed at least three holders to hold the weight. 

I made two holder models, one is just mirrored version of another, it is needed if holders are mounted on opposite sides of the Skadis boards.

I used  22 mm wooden rods, I oiled them with linseed oil, but it is not necessary. I also made end stops for the rods. Those are not necessary since rod is held pretty tight, it just looks nicer. I used 3 mm wood screws to hold them connected to the rod.

I printed holders in PETG and PLA, both works just fine. 

Supports are needed for L shaped hooks.
