IKEA Kallax shelf / shutter

Hello Maker Community, Today I would like to share one of my first projects with you. It is a roller shutter designed for an IKEA Kallax shelf. The assembly is very simple and does not require any glue. Only a rubber mallet is needed, mainly to make assembly easier. The system is mounted directly to the Kallax unit using 4 × 25 mm Spax screws. The components include sufficient mounting holes to install multiple roller shutters side by side. I recommend using two screws per mounted component.All components are mirrored except for the roller shutter end profile. I printed the roller shutter using both PLA and PETG; both materials work flawlessly. The shutter moves smoothly and does not jam. One limitation is that Kallax shelves are not manufactured with tight dimensional tolerances. As a result, the front guide rails may occasionally have 1–2 mm of play.IMPORTANT!!! The length of the strips with the 5 holes must be checked and, if necessary, adjusted in the studio. Boost MeI would greatl
