A 3D printable, resizable container engineered with precision threads, a modular seal system, and commercial freedom.

Details

Smart design: Gradient PLA demo shown. Includes container, lid, and O-ring files. Standard O-ring size included, or resize and print your own in TPU—or even mold in low-durometer silicone.

Sealed + customizable: O-ring ensures tight closure. Design files allow resizing for different volumes. Soft durometer recommended (30 or lower) for proper lid alignment.

Expandable system: Shock-absorbing insert and alternate lids coming soon (sold separately).

Maker-ready: Includes STL (print-ready) and STEP (editable) files for full customization.

Proven settings: Print angled with supports for strength. Tested at 5 walls, 0.2 mm layers, 25% gyroid infill. Fits 256 mm build plates (scale down 5% for Bambu X1C/P1S).

Commercial license included: Print, sell, share, or modify—no restrictions. (Just give Thread & Signal a shoutout if you’d like.)
