Description
If you’ve ever tried to keep a slim 8.4 oz Red Bull can upright in a car cup holder, you know the struggle. My 2013 Toyota Corolla constantly let the can tip, rattle, or straight-up fall over. After one too many spills, I designed this simple one-piece adaptor to securely fit a slim Red Bull can in a standard car cup holder.
The adaptor has a gentle taper from top to bottom, allowing it to fit a wide range of cup holders—not just the Corolla. Just drop it in, slide your Red Bull into place, and enjoy a snug, wobble-free fit.
✔️ Designed specifically for 8.4 oz Red Bull slim cans
✔️ Universal fit thanks to a tapered outer wall
✔️ One-piece print for maximum strength
✔️ No supports required
✔️ Stable, spill-reducing design for daily driving
Material: PLA or PETG recommended
Infill: 20%
Supports: None
Wall Count: 2–3 walls for strength
Layer Height: 0.2 mm works great
Orientation: Print upright (opening at the top)
No sanding required—just drop it in your cup holder and you’re good to go.
If you want extra grip, adding thin stick-on rubber pads to the bottom can help prevent sliding.
I love Red Bull. My cup holder does not.
After repeatedly spilling cans in my Corolla, I finally printed the solution I wish Toyota included from the factory. Now you can use it too.
Tested in a 2013 Toyota Corolla
Should fit any standard or slightly oversized vehicle cup holder due to its tapered design
