🔥 Official Entry for the "Makers Head Outdoors: Summer 3D Printing Challenge" (Track 1: Hardcore).
While engineered for hardcore hiking and trail running, this versatile gadget is also a perfect fit for Track 2 (Outdoor Lifestyle) and Track 3 (Summer Fun) to keep your drinks secure anywhere on the go! 🎒🍹⛰️

Tired of stopping and awkwardly reaching for your backpack's side pockets just to get a sip of water while hiking? This rugged, high-utility bottle holster mounts directly onto your backpack's shoulder strap, keeping your hydration always within arm's reach and ready for action! 🌊

🎯 Key Features:

• 🔒 Secure Lever Lock: The integrated mechanical lever tightly clamps onto your shoulder strap. It ensures the holster stays firmly in place without sliding down, even during steep descents, heavy vibrations, or trail running.
• 💧 Anti-Drip & Drainage Slot: Features a smart, built-in drainage channel at the bottom. If your bottle leaks or sweats due to heavy condensation, the water is safely routed away from your clothes and backpack equipment.
• 🛡️ Rugged Circular Design: The sleek, full-wrap circular geometry evenly hugs the bottle. This prevents annoying rattling, wobbling, or accidental pop-outs on rough terrain.
• 🛠️ Zero-Nut Hardware: Engineered for maximum simplicity. The design relies on just two standard screws that thread directly into the plastic—no complex brass inserts or nuts required.

📐 Technical Specifications:

• 🍼 Maximum Bottle Diameter: 70 mm (7 cm) – optimized for standard cycling bottles, slim insulated flasks, and standard 0.5L sport bottles.
• 🎒 Backpack Strap Width: Perfect fit for 20 mm straps (supports up to 25 mm maximum thickness).

• 🔩 Required Hardware: 2x M3x8mm screws.

🖨️ Print Settings & Recommendations:

• 🧵 Material: PETG or ASA is highly recommended for outdoor use due to its UV resistance, durability, and essential flexibility for the locking lever. PLA can be used as a basic alternative, but avoid leaving it inside a hot car.
  
   

🔧 Assembly Instructions:

1. Place the holster backplate behind your backpack shoulder strap.
2. Position the main body over the front of the strap and align the screw holes.
3. Insert the 2x M3x8mm screws and tighten them gently until the clamp firmly grips the strap. Do not overtighten to avoid stripping the plastic threads.
4. Slide your 7cm bottle in, snap the lever shut, and hit the trails! 🥾⛰️
