Are you a flight simulator freak like me and always wanted that throttle quadrant. Now you can build it with as many axis as you like!
Its driven by an Arduino Leonardo that can handle 6 axis, but if you want more just add another and connect them all to the computer.
My plan is to make some holes in the cover to add buttons.
Knobs will come soon. Everything is still under development.
Use Linear pots!

Print 2 side cover.
Print 1 potholder, stick and cover for each axis.

TEST The holes on the stick before printing alot, change tolerance in scad file if it don't fit good.

20cm M8 rods and nuts works good for 6 axis.
