Ender 3 Y-axis Idler Assm for Motor Relocation

thingiverse

So I wanted to upgrade to a larger motor and add a dampener for the y and x-axis on my Ender 3. It turned out the motor was far too big, so when I went to make a whole new bracket, I had an idea: just flip the Y-axis bracket vertically and mount that way. The new stepper clears the bed leveling knobs by a few millimeters with the plate upside down, but I now needed a new Idler pulley system to keep it from catching on the 2040 bar. Since I have a number of GT2 pulleys sitting around from my HEVO build, I decided to put them to good use. It's always great to have spare GT2 belt pulleys around. Final Parts List: M3x16 machine screws (designed for socket-cap style): 2 count M3 Hex Nuts: 2 count GT2 20t Toothed Idler Pulley, 3mm ID: 1 count 1 GT2 16t Smooth Idler Pulley, 3mm ID: 1 count GT2 Belt: approx. 30.0625" (30 1/16 inches) or 764 mm length GT2 End Crimp: 2 Count It's been in use for over 40 hours of print time now. It hasn't failed and has actually helped reduce my Y-axis ringing I was having (0.9°/step motor with more torque might have helped too...). All the links in the parts list are listed in custom section as well for those who hate blind links.
