Refill travel-sized toothpaste tubes from full-size tubes—save money
Threads screw both tubes together for mess-free transfer
Short 20mm versions let tube ends kiss—no cleanup needed
Includes adapters for Crest-to-Crest, Colgate-to-Colgate, cross-brand
Perfect for travel and bathroom organization

Stop buying overpriced travel toothpaste. This useful 3D printed adapter lets you refill small tubes directly from your full-size tube, making it one of those cool 3D printed things that solves a real problem. Just screw both tubes into the coupler, squeeze, and you're ready for your trip.

The design features precisely engineered threads that fit Crest and Colgate tubes. Choose from multiple versions: Crest-to-Crest, Colgate-to-Colgate, or even cross-brand Crest-to-Colgate adapters. The shorter 20mm versions are especially clever—when tubes are fully threaded, the ends meet inside, eliminating leftover toothpaste in the coupler.

As designed, the thread fit is snug. If you prefer a slightly looser connection, scale to 102% during printing. A smart bathroom organizer for frequent travelers who want to reduce waste and save money.
