I made this lid from scratch after printing the original model. The sealing now fits the Vtopmart 4l box (and most likely all Amazon clones) very well (diameter is 60.5mm). I also added a stop for the PTFE tube as mine got slowly sucked into the drybox during printing, which is less than ideal.
The threat on the couple is a M10x0.75 which fits the PC10 coupler perfectly.
The hygrometer has a diameter of 41mm

The author remixed this model.
The original model did not fit the Vtopmart 4l box from Amazon. I increased the diameter, made the sealing part longer, fixed the threat on the PC10 to M10x0.75 and added a stop for the PTFE tube
