This is a double ball joint mount for a 120 mm fan for a MandelMax 1.5 or other printer with the same extrusions. The two ball joints make it extremely adjustable and with a decent reach. If you want it even longer you can "stack" multiple Ball2 Parts. I remixed some parts from another thing (link on right). It can be mounted anywhere on the frame you want. Example mounting location shown above. It helps a ton with high speed PLA printing and allows you to really crank it up (rest of machine permitting).  Now included are shorter versions of ball2,connector and base (_S suffix). Instructions: Print one of each but two of the locking bolts. I used PLA and 25% infill for all parts except the locking bolt where I used 40% for more strength. Use a drop of oil or a little grease on the bolt for easy tightening/loosening. I used two small wood screws to mount the bracket to the connector.
