Pint carton cup holder for the square peg / round hole problem

The pint carton cup holder is what you’ve been needing every time you’ve put a half-pint of Turner’s, a small milk carton, or a juice box into your car and watched it tip over the second you took a turn. The CupCrate Pint is a 3D-printed adapter that drops into a standard car cup holder and accepts square paperboard pint cartons. Made in Pittsburgh by Archer Frog Designs.

Square peg, round hole — finally solved

Car cup holders are designed for round cans, bottles, and 16-ounce paper cups. But a huge chunk of what we actually drink in cars comes in square paperboard cartons: Turner’s pint sizes, school-lunch milk cartons, juice cartons of every brand, the drink boxes you grab at a Sheetz cooler. The CupCrate Pint is a specific answer to a specific Pittsburgh-area annoyance: holding a square carton with one hand at a red light because the cup holder won’t take it.

How it works

The CupCrate Pint is a 3D-printed sleeve sized for a pint paperboard carton on the inside and a standard car cup holder on the outside. Drop it into your cup holder, drop the carton into it, drive normally. No clamps, no straps, no weird suction-cup Amazon contraption. Just a sturdy sleeve that fixes the geometry mismatch.

What you get

One CupCrate Pint adapter, 3D-printed in PLA, designed and made in Pittsburgh by Archer Frog Designs. Sized for a standard pint paperboard carton inside; standard car cup holder outside. Available in the maker’s current color rotation; reach out for bulk orders.

Heat and driving notes from the maker

Heat: don’t leave the CupCrate in a hot car for long stretches. PLA softens around 140°F (60°C), and Pittsburgh dashboards hit that on a sunny summer day. Bring it in, or store it in the glove box where it stays cooler. Driving: a cup holder is for safe, parked-and-pulled-over drinking. Don’t use this as a reason to drink and drive distracted. Drive responsibly.

Who this is for

Turner’s pint drinkers. Parents shuttling kids and small milk cartons across the East End. Commuters who pack lunch and grab a pint of juice or iced tea on the way out. Coaches with kids’ juice boxes in the team van. Tailgaters who appreciate the smaller pour. Construction crews who pack a pint instead of a 32-ounce. Anyone who’s stuck a square carton sideways in a round cup holder and thought “this is a problem somebody could solve.”

About the maker

FAQs about the Pint Carton Cup Holder

What size cartons does it fit?

Standard pint paperboard cartons — the kind Turner’s, milk, juice, and similar drinks come in. If you have an unusual carton, measure the base before ordering.

Will it fit my car’s cup holder?

Sized for a standard automotive cup holder. Compact cars and some EVs have unusually small or shallow holders — measure first if you’re unsure.

What is it made of?

3D-printed in PLA filament, made in-house by the maker in Pittsburgh.

Can I leave it in a hot car?

Better not to. PLA softens above ~140°F (60°C), and Pittsburgh dashboards hit that on a summer day. Bring it inside or stash it in the glove box.

Do you have a quart version?

Yes — the CupCrate Quart fits quart paperboard cartons (full Turner’s quarts, half-gallons). It’s also available on YinzMart from the same maker.

Can I order in bulk?

Yes — contact the maker via the YinzMart vendor page for bulk orders. Good for fleet vehicles, family cars, team coolers, or Pittsburgh-themed gift bags.

Heyhey YinzMart peeps!! Its Jeremy from Archer Frog.

What can I say? I make things with my wife that others seem to like. My wife helps and runs a lot of the design aspects and I work on tech, there’s a lot of crossover. Our toddler is a cute little destroyer.

We’re not really here for a long time but we’ll stay for a good time. haha
