Print two copies of the dessicant box in one go. Print the center one from user mediaman3d https://makerworld.com/en/models/66371#profileId-69690 and then you are good to go!
This is a print profile of the wonderful model by user https://www.printables.com/@dietrich https://www.printables.com/model/299215-bambulab-ams-dryer-pod-with-indent-for-ams-fix which works better if you have tweaked your ams due to instability and made some modifications. I changed the outer layer and inner layer speed to 60mm so it has more time to cool due to the intricacy of the model. Nevertheless, easy to print with PLA.
I printed it in Bambu PLA Gray, which inside the AMS looks like it was part of the ecosystem.
Highly recommend!
