Frank Green Car Cup Holder Insert

This is a simple drop-in cup holder adapter designed to securely hold a Frank Green bottle inside most standard car cup holders. The insert features a stepped cylindrical design with smooth internal walls for a snug fit and a stable base to prevent tipping or rattling while driving.

The inner cavity is sized for common Frank Green bottle bases (20oz/595ml and similar). The outer diameter fits typical 70–80 mm automotive cup holders. Drainage holes in the bottom help prevent moisture buildup, and the lightweight structure keeps material usage low. No supports are required, and the model prints cleanly in PLA, PETG, or ABS.
