Upgrade your IKEA Kallax with this precision-engineered Roller Shutter (Tambour Door). This 3D-printed insert fits perfectly into a single Kallax cube, offering a sleek way to hide your items with a smooth, satisfying sliding motion. Video

Key Features:

• Seamless Aesthetics: The 15-slat design features overlapping edges that completely hide the internal joints/hinges for a clean look.
• Engineered Precision: Includes 1 handle slat and 14 standard slats designed with rounded pins for minimal friction in the tracks.
• Two Print Variants:
  • Full-Size: For large printers (single-piece slats and 2-part rails).
  • Split-Size: Optimized for smaller print beds (split slats with alignment holes and 3-part rails).
• Hidden Storage: The rails are long enough to tuck the entire shutter away when fully opened.

Printing Recommendations:

• Orientation: Print slats with the visible side down on a textured PEI sheet.

• Support Material: For best results, I highly recommend using multi-material supports (PLA/PETG interface). This ensures a perfectly smooth surface in the overlap areas to hide the joints and creates ultra-smooth rounded pins that glide effortlessly in the rails.

  

• Assembly (Split version): Use short segments of filament as alignment pins in the integrated holes and glue the sections together.
• Performance: Tested and verified on Bambu Lab H2D and Creality K2 Plus. Movement depends on printer accuracy; if it feels stiff at first, it will wear in and become smoother over time.
• Dimensions: If there is too much play between the slats and the rail after printing, you can print the rail slightly wider. Simply scale it up in the Z-axis only, which will increase its thickness without affecting the overall length or the internal track width.
