Elevate your 3D-printed fashion with this completely no-sew crossbody bag. Designed to be printed flat and assembled in minutes, this bag is the ultimate fusion of utility and modular design.
Whether you are looking for a sleek single-color accessory or a vibrant multi-color masterpiece, this file is optimized for high-end results.

Snapmaker U1: Optimized for multi-color TPU printing. Included project files feature modifiers to help you create stunning color patterns on the flap.
Bambu Lab H model (AMS/AMS lite): Compatible with TPU printing setups for multi-material enthusiasts. I'll design and slightly smaller one to fit the 256x256 bed.
Any 3D Printer: Can be printed as a stylish single-color piece on any standard machine capable of printing TPU.

**Features & Specifications**
Completely Modular: Since the bag uses hardware instead of permanent rivets or stitching, you can swap the flap, strap, or base at any time to match your outfit.
Dimensions: Approximately 7.5" W x 5" H when folded.
No-Sew Construction: Simply fold the sides and "braid" the strap through the integrated slots—no needle and thread required!
