I designed this model, because I found the existing models to be too large and time-consuming to print.

This is a adapter and it is specifically tailored to fit Bambulab spools and can be effortlessly inserted into the empty spool.

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.

I have uploaded four different versions.
two for the half of a spool and the other two versions are a bit higher.
