I redesigned this silica storage box to make handling silica much more convenient. Each compartment features a screw-on lid, which can be swapped out for either a funnel (for easy filling) or a spout (for controlled emptying).

To fit two boxes inside one Samla container, you’ll need to print the following parts:

• 2 × Tray 1
• 2 × Tray 2
• 2 × Cover 1
• 2 × Cover 2
• 4 × Caps

You can also print funnels and spouts as needed.

If you want to design your own caps/spouts/funnels you simply need to add a M24.4mm screw with 3mm pitch over a height of 5mm.
