Brendan, if you open the Altronics page with a D-sub connector of interest, say for example this one, you can click on specifications to get to a mechanical drawings. Also, to the left just above the image of the connectors it says "Amphenol LTW SDB-09PFFP-SL8001". That is the original manufacturer and the part number. This is not what Altronics usually does, only for some more industrial parts.

Glen, we are looking at commercial screw-in silica gel holders. However, the one we found here is VERY bulky. If you know of a smaller one it would be wonderful!!!

Brendan, the RS silica gel holder has a nut and o-ring. The way to do the mounting would be to screw it in properly and then use epoxy or some other strong glue to glue the nut to the box from the inside. Just have to be careful not to get the glue on the thread

However, the size of it is still a problem for the sealed chamber around the sensor. We could drop the idea of having a separate chamber for the sensor only and dehumidify the whole box. Or we could redesign the 3D printed part that the sensor sits on (see Faddy's images) and enlarge the chamber so it can have silica gel insert on a side... somehow...
As Glen suggested, we may have to make our own smaller insert, the RS one is too large.
