3D Printed Ball Shifter Pneumatic Coupler

[Sh1ine]

I know teams have been posting pictures of Shiftier Couplers that they have 3d printed. Is an ABS print holding up to the pressure of the system? The snap rings in our shiftier shaft keep failing. I would like to step up to a bigger bearing with a full snap ring, but I can't do that unless the 3d printers work for this application. What are teams finding out in the testing of these parts?

Has anyone had issues with the snap rings besides us? What have you done to remedy the situation?

Thanks in advance.
