Funnels sized to the actual jar, tank or bottle: inlet, outlet bore, cone angle and spout length, with an optional throat filter and a hook to hang it by.
Free and without an account: type the numbers, watch the live preview, download STL and 3MF files that Bambu Studio, OrcaSlicer and PrusaSlicer open directly. Looking for a ready-made size? The model library has 651 of them, each with its dimensions already filled in.

Add anti-glug ribs: they hold the funnel off the bottle neck so air escapes while you pour.
Your exact configuration is attached automatically, so the bug can be reproduced one-to-one. No account needed.
The machine that generates the models seems to be down or restarting. Your settings are safe in this tab: nothing is lost. Wait a moment and try again.
