Compact TPU Tube Case for Mountain Bike

🧩 About the Model

This is a small, flat, and compact protective case I designed for carrying a TPU inner tube (MTB) in my bags or pockets without damaging it. The idea was to keep the footprint as small as possible — so the valve reaches out of the lid instead of taking up space inside the box.

📐 Dimensions

Inner: 20 mm × 60 mm × 75 mm

Outer: 28.2 mm × 64.95 mm × 92 mm

It’s a tight fit by design, so you might need to work the tube in a bit — but that’s how I managed to keep the case so compact.

🧰 Included Files

I like to share my designs in multiple formats for flexibility:

Standard .stl files for general use

💬 Notes

This is just a personal project I made and decided to share — I’m not a company, just a hobbyist who enjoys designing practical little things. Feel free to modify or improve it for your own setup.
