Designed for use with my existing design tool head parts below:-
Z Axis components are below:-
This design recycles part from large format i3 design.
Please download, use, like & comment.
Some parts (motor mounts) need to be mirrored in your slicer, other are symmetrical so printed as is.
Designed for use with LM8UU bearings and 8mm ground steel rods, Nema 17 motors.
Idlers are of the 12mm, 3mm bore type on amazon / BangGood.
Transport XY, and idler designed to have M3 bolts tread into the plastic without nuts / inserts as there is no load in the shaft direction.
And you are going to need GT2 belts x2 5m length.
Also, your frame needs to be stiff as possible if you want to print at speed.
