Concept - A4 File Divider with lid - large print 320x320mm

thingiverse

**Updated:** A new version of the lid is now available, measuring 319mm wide, just 11mm shy of the perfect fit for 320x320 printers. This design concept has yet to be tested, so use it at your own risk. The hinges may not work or clip together properly, and the lid might not shut securely. Additionally, the patterns and holes along the sides and top are untested, so their effectiveness is unknown. I'm waiting for my first 3D printer, aiming to get a large one like the Geeetech A30. Unfortunately, there's a shortage of big items like file organizers that can fit on such printers. I've created multiple designs in just two days using Tinkercad, but I still don't fully understand the limits of 3D printing. This is my third version of a file organizer, and it needs more work before it's complete. To print this design, you'll need a minimum of a 320mm print bed, as one version of the lid is 11mm too wide. **The Design:** - The top edges are ribbed to allow dividers to sit securely in place. - A grooved base matches the top edges to keep paper from sliding around and prevent dividers from shifting. - Both box front and back are angled at 82 degrees for easy navigation through paperwork. - Patterns and holes along the sides and top help airflow and reduce plastic usage, but they're untested. - Tags are not included for ease of printing and customization if needed.
