Durimoiy Silica Funnel (AU Amazon Bulk Silica)

I needed a funnel to match with the 2LB bottle of a fairly common brand of bulk silica balls available on Amazon AU.

Designed to print unsupported, probably doesn’t even need a brim unless your plate adhesion is compromised.

Mates perfectly with the weird bottle thread, designed to offer a smooth feed path back into the bottle with zero catch points.

Fits other AU brands too, I suspect they're all relabelling some bulk source. Might fit the larger bottles too. If you test this, please let me know.

Carries no meaningful load for any length of time so PLA is perfectly adequate. PETG is overkill and Acrylonitrile plastics wild overkill (but go nuts if you want to).
