Description
A practical and stylish 3D-printed tube designed to safely store and transport A4 documents, drawings, letters, or certificates. Simply roll your A4 sheet along the short edge, and it will fit perfectly inside.
Snap-Lock Mechanism: The tube consists of two halves that securely snap together. Quick and easy access without the hassle of threaded caps.
Lanyard Hole: The top section features a built-in hole for attaching a lanyard, strap, or carabiner for easy carrying.
Smart Design: Features an embossed "A4" label on the bottom half, along with textured side grooves for a better grip when opening and closing.
Compact Size: With an overall external diameter of just 40mm (approx. 1.57 inches), it easily fits into any backpack or messenger bag.
Orientation: Print both parts vertically (flat base on the build plate).
Supports: No supports required! Print-in-place ready.
Material: PLA, PETG, or ABS/ASA. For the best durability of the snap-fit mechanism over time, PETG is highly recommended.
