Venturi

thingiverse

The Venturi fits a standard garden hose and has an air intake that will fit snugly onto an air hose with an inner diameter of 0.5 inch. To ensure no leaks, use thread sealant to secure the connection. During testing, no thread sealant was used, and surprisingly, no leaks were detected. This design allows for print without supports, except for the pre-made support for the air intake. Simply remove the circular support near the threads before finishing the print.
