Silica desiccant box for a filament spool by juholga

This is a desiccant box design I use when storing my spools in vacuum bags. Each spool is stored in its own bag together with the box. This design has adjustable clip contacts so it fits most of the spools OK.
You need humidity/temperature LCD module to seal the box and keep tracking the condition of your stored filaments. The module is low cost, less than 1.5 dollar and they sell them both in Amazon.com and Aliexpress. Just search for humidity temperature LCD and you'll find one. Make sure you buy the correct module without the external sensor wire.
I use in parallel all 3 different clips with different color coding. Just print enough each type so you always have available some to fit both newly made or worn desiccant boxes.
When filling the box first use the large opening on top of the display. After the display has been installed continue topping up using the round hole with the help of the filling tool "tratti_v2.stl". The rounded hole can be sealed using an earplug.
silicabox_suoja_v3.STL is a tray that fits the silicabox. I found this useful when storing ready-to-use replacement silicaboxes in sealed plastic bags.

This is the 3-mm filament clip that I use together with the silica desiccant box. It has closed end which is vacuum bag friendly. The desiccant box has a recess on top that fits together with the clip. Align the clip right next to the desiccant box underneath. This way you can eliminate some sharp edges inside the vacuum bag that can potentially damage the bag.
Print settings
I have used 0.5-mm nozzle and PLA for all the items except the tray which is ABS.
Box I have printed using 0.38 mm layer height and no supports.

Aug 18th 2017: Added a box variant "opaque" + source files. Opaque box I have intended for the use case of non-colored silica beads (no toxic moisture indicators). Also the box can be printed from ABS instead of PLA. ABS is typically available at lower price than PLA and it has a higher melting point. The latter may help recharging of the silica beads inside the container.
