This is my advanced desiccant dryer box system which fits in the bambu spools.

You can print it without support.

Please note, due to some feedback I'm afraid that it might not always fit into all bambulab spools. I will test this again as soon as possible with new spools and create alternative versions.

Update!

I recently encountered an issue with the existing design of filament spool baskets not fitting the latest Bambulab filament spools perfectly. After personally testing and confirming the compatibility problem, I made necessary adjustments to the design. This experience highlighted the importance of continuously updating designs to match evolving product dimensions and specifications.

Following my initial adjustments to the filament spool basket design for better compatibility with the latest Bambulab filament spools, I made further modifications to ensure an optimal fit.

Specifically, I reduced the height from 62 mm to 61 mm and increased the inner diameter by 1mm.

These changes have resulted in a version that fits very well for me.

Additionally, I adjusted the groove to match the changes in the new spools, as the groove's design also differed from the previous models.

Recognizing the variability in spool dimensions, I have also created a version that is 61 mm in height, providing another option for those who may need it.

To assist you in creating the perfect fit for your spools, I have also produced just the inner circle in three sizes:

• the original 62 mm height - old version (V1),
• the new 61 mm height - optimized version (V2),
• and the 60 mm height - optional version (V3).

This allows you to test which version will ideally suit your needs before committing to a full print!

With this model, you can now place desiccants, whether they are loose, packaged, or stored in an AMS dry box, inside the spool.

This enables you to dry your desiccant in a device like the Sunlu Dryer.

However, it's essential to note that the model and the dry boxes, for example, are made from ABS, ASA, PC, due to the higher temperatures inside the dryer.

The model also fits four whole of the following AMS Silica Gel Dry Boxes.

This is ideal because you no longer have to transfer the silica gel pellets.

If you print the model on 60% infill and without top and bottom layers (0 layers), you will also automatically have the bottom as a grid ;-)

And I used 4 walls.
