The ultimate UPPAbaby cup holder for your Stanley Tumbler. If you've seen my YouTube channel, you know I designed this specifically to solve the "tiny cup holder" problem. The official UPPAbaby version is expensive, the clip breaks easily, and it doesn't fit the larger tumblers that many use. This version is custom-engineered for a secure, perfect fit. Key Features: Guaranteed Stanley Fit: Specifically designed and tested for the Stanley 40oz Tumbler with Handle. Fully Reversible Design: My custom-engineered mount is symmetrical, meaning you can snap it onto either the left or right side of your stroller frame. Change your mind? Just flip it and clip it. Upgraded Material: 3D printed using PETG, a high-strength, heat-resistant polymer. Unlike standard 3D prints, PETG won't warp in a hot car or become brittle in the sun. Ultra-Strong Clip: This design features a reinforced, high-stress clip that locks onto your Vista frame. Engineered by Jake Ward: This is the exact design featured on my channel, refined for durability and ease of use (https://youtube.com/shorts/Qmr3shZTt4Q). Important Compatibility Notes (Please Read): Strollers: This has been tested and confirmed for the Vista V3. I have not yet verified the fit for the V1, V2, or Cruz models. Bottles: I know for a fact it fits the Stanley 40oz Tumbler, but I cannot guarantee fit for other water bottles/tumblers. Material PETG (High-Strength Heat-Resistant Polymer)
