Refillable Notebook V2 3D print model

This is an updated version of the original refillable notebook that uses a flexible TPU spine instead of a mechanical, rigid one. The new design simplifies the print, increases flexibility, and reduces wear over time. You now only need to print the left cover, right cover, and a TPU spine. Assembly is straightforward and customizable, with the option to color-swap the covers to give your notebook a bold, personal touch.

This version still uses standard printer paper and a rubber band for page insertion, just like the original, but now requires two unprinted lengths of TPU to thread the covers together—and optionally some glue to help keep everything tight.

Uses:

• Personalized notebooks
• Travel journals
• Sketchbooks or art pads
• Refillable planners
• Gifts for students or creatives

Print Instructions:

• Material: PLA (for the covers), TPU (for the spine)
• Supports: No
• Brims: No
• Orientation:
  • Covers: Flat with the outer side facing up
  • TPU Spine: Flat with ridge facing up
• Color Swap: Optional
  • If you want to give your notebook an extra pop of color, you can swap the color on the last few layers of the covers

• Right cover (file included)

Assembly Instructions:

• Punch out the holes: Use an Allen key to carefully pierce through the thin support layers in the holes on both covers.

  • Thread one TPU cord through the spine and cover holes.
  • Pull tight and tie off the end to secure.
