I designed Joystick Toy in Fusion360 and prototyped it through several stages before landing on this design.  

I only recommend printing this assembly in PLA or a material that maintains dimensional accuracy after printing.  It prints well at 100% but I would recommend printing it at 125%.  The Gcodes listed below are automatically scaled at 125%.  I prefer using .15mm layer heights which seems to work well for threads and the ball-and-socket joints.

I natively design in Imperial measurements so you might have to change your scale to 2540% to get it to convert into Metric but the latest version of PrusaSlicer should notice that it is designed in Imperial.
