Belt tensioner for Y Axis.
you also need:
2 ball bearings for the idler,
1 M4 screw (i used 60mm)
1 M3 screw for the idler
2x M4 Insert nuts for wheel and idler (because hex nuts are inferior)
various washers, nuts etc for fixing it to the extrusion.
The Stepper holders are modified versions of Prusa and Haribo Mod designs
You need to drill a hole for the M4 in your extrusion
Added a version for 2020 although untested.
