Belt driven Z upgrade

These parts are designed to upgrade an existing direct driven 8mm leadscrew to a belt driven.
You can use as many leadscrews as you like.
The bearing mount has the same holes as a Nema 17 motor, so you can use your existing motor holders with this mod.

What you need:
-one motor holder ( it has mounting holes for 2020 extrusion)
-one bearing mount and a kfl008 bearing for each leadscrew

-a closed loop gt2 loop of proper lenght (I use a 600mm for my dual Z)
-Pulleys (one for the motor and one for each leadscrew)
-at least one m3 screw and idler as a belt tensioner (the motor holder has many holes to mount idlers)
-two m5x8mm screws and two m5 nuts to mount the KFL008 bearing.
