This is an offset plate to house a 40x40mm joystick potentiometer on a 20mm diameter gimbal rod. With this, you can comfortably control the joystick without strain or compromising your grip. This is a right-hand version (swap the O and C rings to the opposite sides if you're a leftie). The O ring slots into the horizontal overhead Z axis rod, while the C ring clips and provides support on the right-hand grip. I've left a gap for the connector and built in 4 securing rings that support M3 screws (6mm would suffice - and I only used 2).
