🧩 Modular. Stackable. Limitless.

InfinyStack is a fully modular and infinitely expandable storage container system — designed to adapt to your needs. Whether for travel, organization, or everyday use, just stack and screw together what you need.

If there is any interesst in having larger containers i would be happy to provide some extra print profiles.

🔧 System Overview

The system consists of 5 basic components, all of which screw together:

• 🟫 Base Container (~50×25 mm)
  Comes with a solid bottom and a threaded top. It’s the starting point for every build.
• 🟨 Lid (~50×15 mm)
  A simple cap that fits on the base container or any extension module.
• 🟦 Extension Module (~50×25 mm)
  Hollow inside, threaded on both ends. Stack as many as you like using connectors to create tall compartments.
• 🟫 Solid Connector (~50×20 mm)
  A connector with a solid section in the middle — ideal when you need a bottom between modules. Identified by a horizontal stripe.
• 🟦 Hollow Connector (~50×20 mm)
  Fully open inside. Perfect for combining modules into one long compartment. Identified by vertical stripes.

🧠 Use Cases

Pack three types of pills and your toothbrush?

Easy! Use a base container, three solid connectors plus extension modules for the pills, and then add some hollow connectors, some extension modules, and a lid for your toothbrush.

Add more storage for jewelry, tools, or small items?
 

Just unscrew the lid and stack on more.
