SVEINS ZIP Tagged #1 | Zipper Bag v1.5

Introducing SVEINS ZIP Tagged.

Version 1.5 is now available, with improved bag support and a stronger zipper structure.
Fixed the design flaw where the front and rear zipper stoppers could easily detach, and added an interlocking connection between the solid connectors and the zipper teeth.

A graffiti-textured evolution of the SVEINS ZIP system — a flexible 3D printed zipper bag designed for Bambu X2D, where the zipper is fully integrated and printed as part of the main structure.

Graffiti texture designed through PLA × TPU layering, with no post-coloring. An internal connection system ensures structural stability between materials.

TPU 90A × PLA hybrid printing
Flexible structural body
Fully functional integrated zipper
100 cm printable flexible shoulder strap
Three built-in compartments
Graffiti-tagged surface version

This version marks the first surface exploration of the SVEINS ZIP system, introducing a tagged visual language on top of the original functional structure.

ZIP 1 uses a hybrid printing structure of TPU 90A and PLA, achieving a balance between flexibility and structural stability.

The flexible TPU provides bendability and a soft tactile feel for the bag body, while PLA supplies the necessary structural support for printing, rigid components, and the zipper section.

This combination allows ZIP 1 to maintain a soft, usable experience while remaining stable and functional in practical use.

Using PLA as a support structure for TPU on the X2D can significantly improve the surface quality of TPU prints.

At the same time, features such as “wall embedding into infill” or “interlocking beams” can be used to print PLA functional structures in a single process alongside the TPU body.

ZIP 1 features a fully functional zipper structure, allowing it to go beyond an experimental 3D printed piece and become an object suitable for everyday use.

Notes

Important Notice:
If your slicer software suggests setting the distance between the support surface and the model to 0, please click “Cancel.” Setting the support-to-model distance to 0 may very likely damage the model during printing!

Please do not change the vertical layer order of the parts within the print object, otherwise the print may fail！

First, you may choose either 0.16 mm or 0.2 mm layer height for printing. Testing shows that the 0.16 mm version provides smoother zipper performance and easier support removal.

1. Carefully remove supports after printing. When removing supports from the bag body, you may wet them with warm water (up to 50°C) to make the process easier.
2. Do not forcefully bend any part of the bag body, as this may deform the TPU.

3. Do not apply excessive force when installing the zipper,The detailed assembly instruction PDF has been updated. For the zipper assembly section, please follow the video guide for proper installation.

4. Do not use excessive force when operating the zipper.
5. Do not pull the zipper all the way to the bottom end (as marked by the red arrow in the image). If it is fully pulled apart, the two zipper tracks may separate. In this case, you can reattach it in the same way as reconnecting a regular garment zipper.
6. ZIP 1 and all of its components are released under the STANDARD DIGITAL FILE LICENSE.

Update Plan

1.Improved support and easier removal — updated
