Micro Safari: Upcycled Bug Explorer Jar with Built-in Lens & Moisture Wic

🔬 Turn an Empty Coke Bottle into a Pocket Science Lab!

Don't throw away your empty Coca-Cola bottle—turn it into an incredible, humane observation jar for insects, spiders, leaves, and tiny wonders!

Most store-bought bug jars are either expensive or use low-quality, blurry plastic lenses. This project solves that: by pairing a cheap, crystal-clear 60mm glass lens with the straight section of a standard Coke bottle, you get distortion-free magnification and an eco-friendly build in under 2 hours of print time!

✨ Why this design is different (and bug-friendly):

🌿 Humane Observation (Hydration Port): Insects lose moisture rapidly in enclosed spaces. The base features a smart central port for a small piece of damp cotton. This provides essential humidity and drinking moisture so your temporary guest stays safe, healthy, and stress-free until you release it!

🔍 Huge 60mm Optical Lens: Designed to snugly fit a standard, dirt-cheap 60mm handheld magnifying glass lens (just pop off the plastic handle!). The focal length gives you a stunning, ultra-crisp macro view.

💨 Escape-Proof Air Vents: The rim features radial micro-slits for continuous fresh air circulation while keeping even the most adventurous bugs safely inside.

♻ 100% Upcycled Cylinder: Uses the smooth, crystal-clear center section of a standard Coca-Cola PET bottle. Zero filament wasted printing transparent walls that never come out truly clear!

🎒 Modular & Pocket-Friendly: Easy friction-fit design. Quick to open, clean, or swap out the bottle section anytime.
