3D model description

This is belt drive kit for Z axis of Pro B .
And makes it a single Z stepper.

update: add spool hunger and firament guide.

Please look at the picture to assemble.
The lower bearing is a little loose. I stuck the aluminum tape there.

You have to replace the lead screw with 350mm length. I recommend not a common 4 spiral 8mm feed, but one spiral 2mm feed.

*~brace: use M8 threaded rod as brace which leaved after upgrade to lead screws.

2GT cogged belt 782mm~800mm x1(close end)
694zz bearings x4
M4x30 bolt x2
M4x15 bolt x1

M8 nut x8
