Helpful Tips:
ALL filament shrinks after cooling.
The amount of shrinkage depends on the type of filament.
PLA shrinks about 0.25%
PetG shrinks around 0.35%
Taulman 910 shrinks 0.31%
That means a PLA part printed at 200mm long will be short by 0.5mm.
I scale all my stuff in the slicer to 100.25% to compensate for most shrinkage.
Measure for yourself if you don't believe me!

Humid air is actually lighter than dry air,
so it's best to have the dessicant at the top of a container you want to keep dry.
Check my designs for a dry box you can make.
