Hygrometer + desiccant /silica gel spool inlay

thingiverse

What use does it have if you put desiccant in a bag and vaccum your filament if you don't know if it the desiccant is already too wet or if your stored filament caught humidity while sitting on the shelf for too long? This little box has some space for enough desiccant and also has a snap-in holder for some very cheap hygrometer that you can by on e.g. banggood: https://www.banggood.com/Bakeey-Mini-Portable-LCD-Digital-Temperature-Humidity-Meter-Gauge-Electronics-Accurate-Thermometer-Hygrometer-Sensor-For-Smart-Home-p-1654064.html Looks exactly like the ones that Polymaker uses in their PolyBox Edition II... Be sure to not to (except maybe for 1st layer) use any horizontal expansion setting as the walls are designed exactly for .4 nozzles (3 walls) In case you're having loose silica gel, feel free to put some round piece of paper between the hygro and the gel - there's an explicit platform integrated for that... Suggesting to print with 3 perimerters and 20% concentric infill - just a little to support the roofs.
