Btw. #Creality SpacePi X4 temperature and humidity readings seem to be reasonable. I can confirm the small temperature gradient front to back, but as the filament surface cools quickly this would require precision thermal sensors to not get false readings from the open lid (hot air is blowing out at the back.
Living on the coast, the air is a bit humid, so invested in a filament dryer to help with getting reliable prints, this one seemed to have some pretty decent reviews

Should you leave your #filamentdryer box closed or use a spacer to leave a small gap in the lid? To answer the question I measured using a SHT40 sensor, that can accurately measure rel.humidity <15%.
Turns out, it depends.
If the #petg is still wet, aka in the first 8 hours of drying, using a spacer to circulate more (dryer in terms of absolute humidity) ambient air, does seem to accelerate the drying process.
The shopping spree continues! This time, we’ve added a filament dryer to our arsenal. And not just any dryer—it can handle up to four filaments at once! Ready to keep our materials in top shape for all our printing needs!

First time printing out of a filament dryer. Might be overkill for PETG but hey, it's because I can 😅💁
Grrr.
Der Sunlu-Trocker ruiniert mir meine Drucke. Ich habe da schon einige Spulen durchgejagt und jetzt auf einmal verheddert sich das Filament ständig im Trockner.
Most FDM Printers are also Filament Dryers (with a Little Help)
If you've printed with an FDM printer, you probably know there are many interrelated factors to getting a good print. One key item is the dryness of the filament. When you first crack your plastic open, it should be dry. Most filament is packed in a sealed bag with desiccant in it. But if you have the filament out for a while, it soaks up moisture from the air and that causes lots of problems. [Design Prototype Test] has built and bought filament dryers before, but now he would like to point out that every FDM printer with a heated bed can act as a filament dryer. You can see the details in the video below.
It turns out that the idea isn't original, but it doesn't seem to be one that has caught on. What the video shows though, is to take the idea and run with it. A 3D printed support sits on the bed and accepts a cheap PC fan. The whole affair gets boxed up with cardboard and can dry the filament.
The first test worked well, although the support was made of PLA and didn't survive well. An ABS support tower was the answer. We hoped there were STL files for the support, but, apparently, they are only available to the channel's supporters. However, a few minutes in any CAD program should let you duplicate the support easily.
The video mentions that the cover box could probably use more insulation. We would have been tempted to line the box inside and out with cork which is easy to work with and a great insulator. If your printer has a heated build chamber, you wouldn't need the box anyway.
The video wraps up with how to store filament so you don't get moisture in it to start with. He mentions vacuum chambers and reptile heaters. We've used a sealed container and few pounds of unused crystal kitty litter which is just a cheap way to buy silica gel.
We saw [Richard Horne] building a dry box years ago. Food dehydrators seem to work well, too.
