Hybercube 3d printer side-grade kit

I remixed a few of the parts in the hypercube kit to adapt it to the parts i had on hand

-XY Joiner uses a pair of LM8UU bearings to reduce play on the Y axis rod, the rods i have are ~7.91mm instead of true 8mm, so the bearings have a bit of slop in them, the dual bearings tighten it up significantly. also adapted to use 8mm rod on the X axis

-idler adapter to 4mm and 5mm idler bearings ( i am using idlers with GT2 teeth) which i happened to have on hand

-z leadscrew holder adapted to use normal 608zz instead of flange bearings

-beefed up z nut clamp, the one I printed kept snapping when I bolted down the Z nut holder on the side of the z carriage
-also designed this brace to convert the printer into a heated enclosure in addition to adding bracing. http://www.thingiverse.com/thing:1799079
