In-Spool Desiccant Holder with Mi2 Hydrometer

Remix of compute4you's Silica gel box for BambuLab spools - I've included a Mi2 Hydrometer (humidity sensor) holder to the original model so you can monitor your filaments humidity and also report into systems such as Home assistant to alert on as you see fit as shown below

These in spool desiccant holders work equally well in Vacuum packed bags or like, I personally use - air tight food containers etc. basically pretty much anything a spool fits in.. as they are in the spool themselves!

May need to remove the Screw supports with pliers (depends on filament as some comes away easier) also adjust the screws on the bottom to get a nice tight fit in the spool.

compute4you also provides a useful funnel that works with this remix - https://makerworld.com/en/models/114674#profileId-123293
