Got it upgraded and printing.
upgraded z axis, LM10UUs all around.
The X Ends are printed. I am printing modified Xends in the video. They combine the plate with the respective end piece and add reinforcement. Will publish once finalized.
ITT: Salvador Dali makes a 3D printer (but seriously what is with that distortion?).
You probably know this by now, but it’s not printing anymore in your video. Also, tighten your x-belt!
I like the filament feeder on the side, it seems like it would keep unruly spools in check.
Overall, I’d rate it delightful/10.
Yeah, filament jammed 
didn’t notice till the video was posted.
I have tightened the x belt actually have changed the x axis.
Printed X Ends with plate integrated and stiffened. http://www.thingiverse.com/thing:436981
