Desiccant Container Holder (for Bambu Spool)

Spool Desiccant Container Holder (For Bambu Lab Spools)

This Spool Desiccant Container Holder is designed exclusively for Bambu Lab filament spools.

 

I originally based my concept on another excellent design from Silvercell, but wanted to explore my own version.

It fits perfectly inside the center hub and stays fully flush, meaning the spool can rest completely flat on your desk, dry box, AMS tray, or any storage surface without wobbling or scratching.

 

Update - Version 1.1 - March 11

Some users mentioned that the original version could feel a bit fragile when pressure is applied to the center. To address this feedback, the model has been improved with an internal reinforcing ring to increase rigidity.   A new Reinforced print profile is now available for those who want a sturdier result.   The original print profile remains unchanged and still provides a good balance between strength, print time, and material usage.   This update simply strengthens the lid and base mesh structure while keeping the same printing settings.

 

The model uses Bambu Studio modifiers for the bottom and cap mesh structure.
⚠️  If you only download the STL, the mesh will NOT be generated. ⚠️
You must use the provided print profile to get the correct mesh patterns.

 

Features

• Designed specifically for Bambu Lab spools – perfect center-hub fit, zero overhang outside the spool.

Printing Recommendations

• Use the provided print profile – required for mesh generation.
• No supports needed.

Material

• PETG for better temperature stability.
• ASA if you frequently regenerate silica beads at higher temperatures or use a heated dry box.

Usage

• Open the container and fill it with silica gel beads (2–4 mm recommended).
• Screw the lid on firmly.
• Insert the container into the inner hub of your Bambu Lab spool and screw the top wheel.
• The spool remains perfectly flat and stable during storage or printing.
• Regenerate the beads when they become saturated and refill as needed.
