This was mostly an experiment for myself. all my designs so far have been done with VR sculpting, which i thought would be impossible to make moving parts within. so i gave it a try and proved myself wrong with this little joystick toy i made for a test. tolerance is pretty tight!
my printer had a hard time with the stock tolerance.
RECOMMENDATION: horizontal expansion = -0.05
-0.05 horizontal expansion if stock settings don't work.
