Foldable Dryer for Hydration Bladders

💧Foldable Dryer for Hydration Bladders (Print-in-Place)

Hydration bladders are designed to stay flat — which makes them a pain to dry.
This compact foldable drying sphere set keeps the inside walls apart so air can circulate freely, letting your bladder dry faster and stay odor-free.

 📐 Two Sizes — Two Uses

• Hanging mode: insert the small sphere near the opening and hang the bladder using the hook. Gravity takes care of the rest.
• Horizontal mode: place the large sphere deeper inside to inflate the shape and improve airflow. Works great when you can’t hang it.

🧩 Includes

• 1× Large foldable sphere
• 1× Small foldable sphere
• 1× Hook
• 1× Storage puck (everything fits inside)

✅ Features

• Print-in-place folding hinges — ready to use right off the bed
• Compact & lightweight — ideal for backpacking or travel
• No assembly required
• Compatible with most water bladders 

Smooth the hinges if needed before first use to ensure free movement.

⚠️ Disclaimer
3D-printed parts are not food-safe by default. If you’re concerned about contact with your hydration bladder, make sure to wash the spheres thoroughly before use.

For extra peace of mind, you can also place the sphere inside a small plastic bag (like a Ziploc) to keep any micro-particles separated from the inner surface of the bladder.
