Y axis sliders for updated tronxy X5S-400

This is a modified cart that has more clearance to be able to hold real pulleys supplied with the newer Tronxy kits instead of the old bearing stacks. The hole for the M5 screw has been altered to not taper at the bottom to fit the longer screws that was supplied with my kit. The holes for the X rail has been shifted to accommodate mounting on the 400mm version. 500mm rails fits well on the Y axis and 550mm on the X-axis
