I designed a stackable, space-saving funnel set that comes in three different sizes, perfect for any kitchen, workshop, or lab setup.
The funnels neatly nest inside each other, saving valuable space wherever you store them.
Each funnel has grooves along the spout that allow air to escape while filling, so liquids flow smoothly without bubbling or splashing.
 

I printed them in PETG, so they’re durable and heat-resistant, making them safe for hot fluids.
