Mason Jar Funnels

Simple canning jar funnels I designed specifically for both small and large mouth jars, ensuring a perfect fit every time. I chose PETG as the material of choice due to its food-safe properties and ability to withstand hot liquids without compromising integrity. To achieve optimal results, printer settings will need to be adjusted according to your specific printer model and type of filament used. A crucial step is setting up your slicer to print from outside in, starting with the outer wall and stopping at the inner surface. This unique approach leaves a smooth interior finish on the funnel while containing any zits or imperfections on the exterior, making cleaning significantly easier and reducing areas where bacteria can accumulate. Both funnels fit comfortably within the neck of their respective jars, with the wide end of the small mouth funnel designed to be slightly smaller than that of its large mouth counterpart. However, I decided against enlarging it, as both funnels perform admirably in their intended roles. Feel free to modify them as needed to suit your specific requirements. These funnels were created using Tinkercad, allowing for seamless modification and customization. The wall thickness of approximately 1.5mm ensures durability while maintaining a compact design.
