I liked the dual flange spool weight design and as my silica is supplied in zip lock bag, I needed a way to get the silica in and out without spilling it everywhere. I printed a “Fast and precise spoon” but found it too slow for the amount of silica beads these spools hold.

I didn't want to waste a stack of support, so I've opted to require using CA glue to connect the funnel to the screw-top lid.
For those that want a single piece, I've included a model that doesn't need CA Glue, but will require support to print.

Note: It might be a slight oversight in how much silica beads BOUNCE off the flat faced funnel bottom. No false advertising here - even managed to catch a few beads that bounced out of the funnel in the cover photo.

I usually just cover it with my hand as I pour and nothing escapes.
