3D Printed Ball Shifter Pneumatic Coupler

[Rstrzelecki]

At first we 3D printed a new one out of abs to fit the 1 1\16 bore cylinder we wanted to use but after about a day of use it blew out and we have since been using an aluminum one that threads on the the cylinder and is slotted to allow the bearing to slide in.

We were having problems with a 3d printed coupler so we designed a bearing block style coupler for 1-1/16 bore cylinder and have not had a problem yet. The bearing is now half inch OD and we use the same snap rings without a problem.
