Interchangeable funnel outlet

This is a interchangeable funnel outlet with 8 different sizes and 3 different lengths. This can be used for a variety of applications. Some examples could be use in the kitchen for food items (liquids, spices, etc) and for automotive applications, such as small lawn mowers, weed trimmer, etc. Also could be used for arts and crafts, and in science experiments. 

Print Instructions: When slicing sizes 5-20, make sure the “Ensure vertical shell thickness” setting is enabled. A 5mm brim is highly recommended for adhesion and supports would be helpful to keep the print from being knocked over during printing. Sizes 25-40 can print without a brim and “ensure vertical shelf thickness” can be disabled. I would recommend 2-3 perimeters for all sizes, and 3-4 solid layers. Also, set the infill to 10-15% with your desired infill pattern. When slicing, the funnel base, you can have 2-3 walls with zero infill ABOVE the threads. PLEASE NOTE, that the outlet is measured by the inside diameter. The outside diameter is 3mm bigger.

PRINT WITH THREADS FACING UP.(Threads shouldn't be touching build plate)

If you do not see a size you like, let me know in the comments section and I will try to upload your requested measurements. 

Lastly If you are a solidworks user, I have included the .sldprt parts files.
