This is a remixed of a Y Axis Dual Damper Mount For CR-10/CR-10S (by mce076). ALL credits to original creator. Much appreciated. I just remix for my FLsun.
This heavy duty mounting bracket can support 60mm motor for high torque.
This bracket was intended to use with this heavy duty Y Belt Tensioner that I remixed but can be use separately if the height of the belt is ~20mm.

You should double check your bed clearances and also the height of your belt before you print.
