I designed this sled tower for organizing filaments inside one of my pieces of furniture.
Having many reels and many colours, I thought I could organize the spaces as best as possible.
Being designed with a slide, it is possible to remove and insert each reel as desired and it is also possible to turn it upside down to make multiple rows both above and below a shelf or shelf.
I printed everything in PLA and PETG, as desired. Only 2 screws are needed for each individual tower.
