About this 3D model
Some kits of MK3S from Fysetc need to raise the rods of the Y axis about 0.4mm in order to avoid the frame. I have created two versions: 0.4mm version is marked with 1 dot on the side (as you can see in the picture) 0.6mm version is marked with 2 dots on the side (as you can see in the picture) I highly recommend to combine this models with this bearing holder
