T8 CNC Z Axis bearing block

I bought a T8 CNC from Gearbest a while back, and the Z axis slop was awful..
I made a simple IGUS RJZM-1-8 Drylin bearing holder to cure this..
It has totally eliminated all z-axis slop on my T8 CNC..
The original M3 plate spacers are crap, and have been changed for M4 x 25mm..
I've also fitted my motor cooling vent, also on thingiverse, and a few other bits, as well as a separate deck to house the PSU's and associated junk!!
