As a few people have tried different mounts to reduce weight & ghosting, I designed my own on their theme, using top/bottom bearings for ghosting. Bearings are 3D printed in PETG/Nylon & sized using an 8mm H8 reamer as are the X axis bar bores.
Brass M3 inserts & M3x5mm grub screws are also required.
I've made the body slightly longer to hide the retaining collars for X axis.

Using 14mm drill by hand to true up bearing bores & recesses for retaining collars.
Size bearing after fitting & make sure reamer goes through both bearings to make sure they are aligned.
