Modular Twist-Lock Square Containers — 100% Support-Free

A fully modular, stackable, and space-saving square container system designed for functional storage. Whether you need to organize your workshop screws, kitchen spices, or 3D printing accessories, this system scales to fit your needs perfectly.

📐 Modular Sizes & Grid Alignment

All containers and lids are fully compatible and interchangeable. The dimensions are mathematically optimized to stack and tile perfectly together. Because they increase in consistent increments, you can combine different smaller sizes next to a larger one, and the total width or height will remain perfectly flush and aligned!

• Widths: 50mm (~2") / 75mm (~3") / 100mm (~4") / 125mm (~5") / 150mm (~6")
• Heights: 50mm (~2") / 75mm (~3") / 100mm (~4") / 125mm (~5") / 150mm (~6")

Mix and match to create your perfect storage grid without wasting any space.

🔒 Secure Twist-Lock System

Features a robust and smooth Twist-Lock mechanism that secures the lid with a simple turn.

💧 Optional TPU Gasket Lid

Choose between two lid variations depending on your needs:

• Standard Lid: Quick print for everyday dry storage.
• Gasket Lid: Features a built-in groove designed for a custom TPU seal/gasket to keep your contents airtight and moisture-resistant. (Note the seal installation direction when assembling)

🛠️ Key Features & Print Advantages
