About this 3D model
Like many others, I store my filament spools in IKEA Samla boxes. This container is designed to be attached to the lid of such a box using strong double-sided sticky tape. It holds approximately 180g of silica gel. You can close it with the included lid or with a standard PCO-1881 lid as used in most PET bottles. A funnel is also included that is flattened on one side so it can be used while the "bottle" is stuck to the lid of your filament box.
