I have added a big version to accommodate for V4 and for Xenomorph with Eddy

You need to orient the part in the slicer
this is a simple idea not only to keep the belts in place and aligned but you can also stretch them to fit your new build like Xenomorph, Spartacus, Shroud V4 or any other toolhead that you want to install in your 3D printer. can be used in any Voron stile gantry 3D printer.
Print settings

35% gyroid infill

The author remixed this model.
When we made the back plates to can install Spartacus on the Stealth Changer I saw the belt helper they use so we made one that suit our needs.
