FLSun QQ-S Arm Spring Clips

Worked ok in PLA, can be printed vertical without a brim if your bed adhesion is good enough.

I used springs from an amazon selection pack, if the springs are too strong then it can twist the carriages, and will exert a centring force on the effector.

Could probably benefit from a rework bringing the attachment points closer in to the arms, as this reduces twisting forces on the carriages when the effector is not in the centre of the bed
