Modular Backpack Bottle Holder System

This is a complete modular bottle holder system designed for backpacks. It features two bottle sizes (16.9oz and 20oz) with multiple attachment options so you can configure it exactly how you need.

Included parts:

• Bottle Holders: 16.9oz and 20oz versions

• Bottle Holder Attachments: Strap end, Carabiner end, and Male Buckle end (for each size)

• Female Buckles: One for strap connection and one for carabiner

• Split Strap Carabiner Buckle: For easy attachment to existing bag straps

• Split Ring Male Buckle: For more compact attachment

The design is a remix of Jerre’s Sturdy Backpack Buckle, mikerockbennett’s 20oz Bottle Holder, and Dzyn72’s Bag Strap Buckle. All parts are strong, easy to print, and highly interchangeable.

Perfect for hiking, commuting, travel, or everyday backpack use. Mix and match components to fit your specific bag setup.

Note: I didn't need supports and used only mouse ear brim. I heated the bottle holder with a torch just below the intake hole and used a bowl to get the bend. I figured this would be better than printing weaker layer lines at the bend.
