6" adjustable vent
Posted: Fri Sep 30, 2016 12:31 pm
This was a project for the day job and my most ambitious build so far. I design bottling machinery for a bottle cap company. We sometimes blow bottle caps through 6" stainless steel tubes to get them from point A to point B. In order to limit the speed of the caps at different points in the tube we want to test venting some of the air after the caps are part-way through the system. This is a 6-piece build with 42 stainless-steel rods creating the cage. The 6" tubing will (hopefully) slide into each end and we'll be able to open the vent to different amounts to see how it impacts the velocity of the caps downstream. I have a spring-loaded ball for a detent to give it 10 positions between open and closed.
This is all PLA. It's not for long-term and I felt more confident about getting straight, true builds from PLA than ABS. PETG wouldn't have been a good choice because sliding parts tend to be sticky with PETG.

I wanted the two inner sleeves to be orange, but I ran out of orange filament due to a failed build.
