I'm planning a keezer collar and I wanted to know if anyone has come across any more elegant solutions to running the temperature probe through the collar than just drilling a hole or just running under the gasket. I will be attempting to ferment and serve in the same keezer so I plan on running two probes one for keezer temperature and one for controlling a heating pad for the fermentation vessel. I know its simple enough to drill a small hole and fill with some silicone but I would rather not have it be permanent so it is easier to clean or remove. I found I've combed through countless threads and haven't been able to find anything like a 3.5mm bulkhead or what seems like the right grommet/gland for the job so I figured I would reach out to see what people have done. I might be overengineering this aspect of the build but I figure I might as well do it cleanly if there is an option. Thanks!
