Adding oil to the final drive and front diff can be a pain so I made these adapter "bolts" that screw into the fill ports and allow you to hook up some 1/2" PVC hose to make it easier to fill.
I printed mine in PETG at 0.2mm layer height and they work great. Just be careful not to break the threaded portion off when screwing them in. They don't need to be tight. You could probably print them in TPU as well.
These should work on all years of the YXZ to my knowledge.
I've included the original Fusion F3D file as well so you can modify tolerances if needed.
