Update 5/1/2024
I created a wider adapter for the small silica box that makes it possible to fill silica easier. To use it you need to remove the lid of the small silicabox and fill it up. The adapter suits the big funnel.
Both versions of the small funneladapter is included in the -v2 print profile.

I created a funnel for the excellent "Drybox for AMS" (https://makerworld.com/en/models/67281#profileId-71174)
The funnel itself fits the bigger box. Apply the smaller funnel to the bigger and you can use it for the small box also.
