Please wait before printing one of these it is still a WIP - pictures soon.
Update , printed the lm8uu zaxis carriage and it needs a bit of redesign. please hold off for version 2 unless you want to put tape on the bearings before inserting them.
also you need a drill and a peice of quarter inch smoothrod to make a short reamer tool for the vertical holes in the blocks.
i decided to go with 4.4 mm ballchain

the blocks print standing up without supports on my printer.
my next version of cubit will be using 2020 or 3030 printed tslot 3d hopefully more efficient use of plastic and time, if all goes well with the strength tests, gluing threadrod in place as joiners also do a melt in the middle with 2 peices.

also the xcarriage is upside down in the pictures the arrow should go downwards. if using alternate model file then it goes upwards and you file some of the top off.
new style of reprap using 3'x6' 4 peices of 1/4 inch threadrod - 12 x 18" pieces of 1/4 inch threadrod you can get 6' lengths at homehardware for 5 dollars each. going for a nice ultimaker / davinci style clone.
maybe leave extra on the threads if you want till i perfect the design.
lm10uu and lm8uu version of the z axis
