I agree with SeanB that the joiners need to be screwed as well to prevent vibration from shaking the joins apart.
I realys like to see it printing, a specialy using it's two printheads together. I realy like the idea with those two heads. Unfortunaly my little reprap prusa mendel i2 hasn't the space for two printheads and i made some mistakes as i build it yust like the online documentary. So now my x axis roads a a little to short so my Printhead can't use the full size of the 20*20cm build platform.

I've been looking at the video a few times...
It's brilliant, love it, want one, no budget, will have to wait, darn.
... I can see a lack of rigidity/damping when it moves side to side, it kinda annoys me.
You could use triangular 10/15cm stiffeners in each corner (relative to movement) simple screwed in.
It would probably help precision.
Being a cheap arse, it'd probably cut-up old/defect PCB to make them...

Checked it out,
Yeah, the junction parts are plastic... Great for damping but this this is going to need stiffeners or it will transform itself into a very expensive plastic life-cycle fatigue experiment.
