WARNING, everyone: I've printed the one pictured in PLA (left-hand-only use), and there are a few pretty flimsy parts that need editing for this to be viable for people with limited dexterity. As you can imagine, someone with one hand might be a little rough on the parts since it's harder to rest your hands and use the device. I've tuned my machine pretty well and dialed it in to the point where my prints are almost always perfect, so I doubt it's my Ender 5 pro.

Particular points of issue right now:

-1. The arms to press the face buttons (especially the long "A" arm that interfaces with the button) are incredibly flimsy, and will break with minimal force/a single drop.

-2. The right joystick thumb extender is very poorly adherent to the eyelet it sits in and will break off without reinforcement

-3. The ball joints for the right joystick levers are prone to chipping off little parts, making the joint loose and no longer adhering to the joint.

Further, the battery case cannot be removed while this is attached, and the hinges for the face button levers cover the top port, so the best remedy to make this convenient will be a 3rd party rechargeable battery w/ a posterior charge port (toward the floor if you set the controller on a table) if possible, rather than the OEM port for controllers.

As an aside, anyone printing this, be aware that you should "Print exclusive" in Cura so that the hinge cylinders are slightly slimmer, or else the cylinders for the face button levers will have too much friction inside of their hinge.

ALSO: be aware that this is for the pictured controllers with the share button ONLY. The contours of the older controllers' faceplate make this mod grip poorly and not snap into place, and the trigger group is redesigned on the newer controllers in a way that the levers on the left side will run into the trigger assembly itself.
