The goal of this design is to mount the lubrication to the spindle and be able to pipe in air from a pump mounted elsewhere on the machine. This design should be much more cost-effective than a commercial system.

We used a many models found on Thingivers. We modified one of the Ball and Socket pieces to add a tab so it was easier to hold and tighten. Additionally, we had to create a few custom pieces for mounting.
