Tevo Tarantula Upgrades.

Tevo tarantula bed rails upgrade , dual z axis upgrade , y & x pulleys , modified z axis carriage , z axis rod nuts holder, z axis reinforced stepper brackets, x axis stepper mount , z endstop holder.

there is a z axis bracket that i can not found the file anymore,both myne and original.

and there is another design of z axis carriage kit

the pulley should be printed with the extensions that goes in the frame ponting up in the slicer , then scaling only on z axis, you put to 60mm insted of 56.. This, to make some space for the roll that goes inside.
then the turning wheel ( the original one ) you scale it to 11mm xy
