Modular Test Tube Tree Tower 🌿

A stackable, branch-based stand system designed to securely hold standard test tubes in a vertical, tree-like layout. Ideal for chemical labs, educational setups, or stylish experimental displays.

Design & Specifications:

• Branch-Based Modular Structure:
  Each branch unit includes 7 equally spaced holders arranged radially around a central hub. Branches are designed to stack vertically, allowing you to extend the tower height as needed.
• Standard Compatibility:
  Supports test tubes up to 16 mm in diameter (standard size) and up to 150 mm in length, covering a wide range of lab requirements. (I used the Pyrex 16mm x 150mm Test Tubes for this design.) If you need any additional size, please let me know, and I can modify and publish that for you!
• Secure Tube Holders:
  Holder arms are designed with circular slots that provide a snug fit and raised support lips to keep test tubes upright and stable.
• Central Trunk Column:
  Acts as the core structure. Each level stacks via a simple press-fit mechanism, with optional bonding for permanent assembly.
• Heavy Base with Drip Tray:
  The weighted wooden-style base improves stability and also functions as a drip tray for any liquid overflows or rinses.
• Top Cap Closure:
  A matching tip cap is included to cover the topmost branch, offering a clean finish when no further extension is needed.
• Assembly Tip:
  While the parts are designed for friction fit, super glue is recommended at connection points for added strength and long-term stability, especially if the tower will be fully loaded or frequently moved.

Functional Use:

• Suitable for any chemical-related test tube storage, reactions, or display.
• Perfect for lab organization, classroom demonstrations, or science-themed decor.
• Modular and customizable — add/remove branches based on tube quantity or height preference.

• Easy tool-free assembly and cleaning.
