Turn your used 2L PET bottles into modular, reusable containers! This screw-together splice system lets you mix and match bottle sections without glue, tools, or frustration. Whether you're building a bug viewer, dry storage bin, or creative vertical garden structure, this system gives you endless flexibility.

Features:

• Press-fit & screw-together — no hardware needed
• Compatible with common 2L PET bottles (cut-to-fit)
• Available in solid, vented, and splice ring options
• Threaded A/B parts connect any top to any base
• Cut Guide for clean, level cuts
• Designed for dry applications only (not leakproof for liquids)

Example Uses:

• Bug viewer
• Seed starter
• Food-safe dry storage (e.g., rice, oats)
• Workshop organizers
• Kid-friendly stacking projects
• Compost filters or leaf traps (dry only)

Important Notes:

• This design is not water-tight — it’s ideal for dry materials or aerated systems
• Apply glue for permanent or heavy-duty assemblies
• Designed specifically for 2L PET bottles — cut and align carefully

Bottle Cutting Tips

For best results, use a sharp utility knife or heated blade and the included cutting guide ring to mark and trim bottles evenly. Always cut just above the molded shape of the bottle base or below the neck taper for the best press-fit. Apply glue if permanent or heavy use is expected.

STEM / Educational Use

This system is a great hands-on way to teach kids about sustainability, recycling, and mechanical design. Combine with classroom activities or science projects to create bug viewers, moisture-free specimen containers, or modular build-and-learn kits.
