Mini Drone Stick Extender

These are a very simple pair of stick extensions for my areix mini drones. Got tired of wrapping my thumbs down to the small sticks, so I extended them by 15mm or so to more fit my grip.
Hole is 3mm x 7mm. Top post is the same.
These were designed for the Areix mini drone controllers but could be customized to fit any similar stick style.
So far this design has worked well enough for me to retrofit my Entire drone fleet with these and similar extensions for the larger controllers.
