This Silica Box is for the AMS Hydra Mod, but it also works perfectly with the standard AMS.
It fits perfectly and the volume is larger than in other versions. There is also a version that support a Hygrometer. This is the Hygrometer I used https://www.amazon.de/dp/B0BKZXFDVX
Each box holds around 100g of silica.
The version without Hydrometer prints without any supports. The Hygrometer version needs some supports at the top of the round cutout. I used tree support that starts from the print plate.
The print profile I added is for the version without hygrometer.
