I printed the v3 desiccant boxes by G.design, today, and promptly spilled desiccant on my floor with a funnel that was designed for something else.
the entrance on the side containers is small, I wanted this funnel to fit snugly in—without making you remove the lid.
because you have to hold the smaller funnel in place if you use it with the main container, I added a larger funnel that fits snugly into that one, too.
entirely coincidentally, the smaller funnel stacks neatly inside the larger funnel.
since they don't have corners, I measured the largest dimension in both directions
I got lousy results in a test version by printing normally, and tried vase mode. it turned out great. so, print settings:
the 3MF files should have these already set, but please confirm.
as always, I included STEP files to facilitate remixes. if there's any interest, I'll clean up my Fusion file and post that, too.
The author remixed this model.

I measured the entrance to the v3 side container, and designed a funnel based on that. it fits snugly into the side container without removing the lid; it also works fine for the main container.
