Upgraded my Geeetech A10M Y carriage to an New Ender3 type. Due to the roller mounts being further apart i had to create a new mount for Y axis end stop limit switch. (see y carriage photo RED and YELLOW circles show the different mount positions.)
To mount to V-slot rails use M4 T-Nuts and M4x10mm screws

up to 0.2 layer height would work well also, printed with 4 walls and 1mm top and bottom layers for added strength, especially around screw holes.
