Here is a model designed for Sun eBox / System for drying your filament .
This model is inspired by others I have seen here and there.
Print with support and add a support blocker at the level of the thread.
To ensure that the valve is screwed in properly without damaging the threading, it is advisable to deburr thoroughly using a deburring tool.
I bought these items from AliExpress but should you be able to find it also on amazon:
