Keep the party going without ever reaching for another drink. This engineered multi-can koozie system holds 2 cans by default and can be extended to hold up to 4 cans using the included extender. When you finish a drink, just push a new can in from the bottom — the empty ejects out the top automatically. Simple, satisfying, and insanely practical. 🔥 Key Features Continuous Feed Design Load from the bottom → fresh can appears at the top 2-Can + 4-Can Configurations Includes extender to double capacity Threaded Cap System Top + bottom caps screw on securely Integrated TPU Retention System Flexible internal seals hold cans in place while allowing smooth movement Stability Base Option Wider bottom cap included for better balance Single-Material Version Included Alternative parts for users without TPU capability 🧊 Perfect For Beach days Camping trips Tailgating Lake days Backyard parties 🛠 Printing Info Designed for PLA + TPU (recommended) Single-material option included (PLA only) No supports required Modular components for easy printing 📦 What You Get Standard 2-can system 4-can extender system Threaded caps (standard + wide base) TPU + non-TPU versions 🔍 Keywords 3D print can koozie, beer dispenser STL, multi can holder 3D print, drink dispenser STL, camping koozie STL, tailgate accessories 3D print, party gadget STL, functional 3D prints, beverage holder STL, modular koozie system, print in place drink holder alternative, novelty 3D prints
