Finally, a Cup Holder That Fits YOUR Bottle
Most vehicle cup holders were designed for soda cans and small coffee cups.
Today's insulated water bottles are bigger than ever.
Whether you carry a 40oz Stanley, 64oz Hydro Flask, Yeti Rambler, Owala, RTIC jug, mason jar, or another oversized bottle, you've probably experienced the same frustration:
• Bottle won't fit the cup holder
• Bottle tips over while driving
• Bottle rolls across the floor
• Bottle gets wedged between seats
• Condensation and spills make a mess

Custom Built For Your Bottle
Unlike universal adapters that only fit a limited range of sizes, every adapter is made specifically for the dimensions you provide.
Simply provide:
• Your bottle diameter
• Your vehicle cup holder diameter
Your adapter is then custom manufactured to create a secure fit between the two.
No guessing.
No generic sizing.
No "close enough."
Just a custom solution built for your exact bottle.
Works With Nearly Any Brand
Popular applications include:
• Hydro Flask
• Stanley
• Yeti
• Owala
• RTIC
• Iron Flask
• Nalgene
• Bubba
• Thermoflask
• Takeya
• Mason Jars
• Custom Tumblers
Don't see your bottle listed?
No problem.
If you can measure it, I can build an adapter for it.
Ideal For Oversized Bottles
Many standard vehicle cup holders cannot safely hold larger containers.
This adapter is especially popular for:
• 40oz bottles
• 46oz bottles
• 64oz bottles
• Half-gallon jugs
• Large insulated mugs
• Wide-mouth bottles
Even heavy, fully loaded water bottles can be supported when properly sized.
How to Order Your Custom Cup Holder Adapter
Every adapter is custom-made specifically for your bottle and vehicle cup holder.
Step 1: Tell Me Your Bottle
The easiest method is to provide:
• Brand (Hydro Flask, Stanley, Yeti, Owala, RTIC, etc.)
• Model (if known)
• Size (40oz, 64oz, Half Gallon, etc.)
In many cases I can verify the dimensions using the manufacturer's specifications.
If your bottle is uncommon or custom, measurements may be required.
Step 2: Measure Your Bottle (If Needed)
The preferred measurement is the bottle circumference at the point where it will sit in the adapter.
Option A – Flexible Measuring Tape
Wrap a flexible sewing tape around the bottle and record the circumference.
Option B – String Method
- Wrap a piece of string, ribbon, or paper strip around the bottle.
- Mark where it overlaps.
- Lay it flat.
- Measure the marked length using a ruler or tape measure.
Millimeters (mm) are preferred for maximum accuracy, but inches are also accepted.
Step 3: Place Your Order
Include the following information with your order:
• Bottle brand
• Bottle model
• Bottle size
• Bottle circumference (if measured)
• Vehicle make/model/year (optional but helpful)
• Cup holder opening size (if known)
I'll use this information to design and manufacture a custom adapter specifically for your setup.
Color Options
Standard color is Black.
Custom colors may be available upon request depending on material availability.
Custom colors may require additional processing time and may incur an additional charge.
Designed, Made, and Assemble in the USA
Every adapter is designed and manufactured after your order is placed. Each one is individually 3D printed from PETG plastic and made to order.
Because each one is custom sized, you receive a product built specifically your bottle.
Whether you're carrying a giant 64oz Hydro Flask, a Stanley tumbler, a Yeti Rambler, or even a mason jar, you'll finally have a cup holder that actually fits.
