Belt driven Z upgrade

thingiverse

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. my rod holders: https://www.thingiverse.com/thing:2851231
