These brackets allow you to get the maximum Y travel possible on the ender 5 frame. When converting an ender 5 to the ZeroG Mercury1  with the EVA tool head, some Y travel is lost because the rear mounted fan hits the Z guide rod brackets.

To maximize Y, you must first remove the unnecessary top & bottom 2020 extrusions that the ender 5 Z guides and stepper are mounted to. They can be mounted directly to the rear frame. This gives you 20mm more travel. 

Then use these printed brackets to replace the upper Z guide rod brackets. They mount to the bottom side of ender 5 frame extrusion. The guide rods can drop down a bit as well.  Now the EVA can travel all the way back to ender 5 frame. Reset your end stop and this will give you 275mm x 275mm travel.

I've included two versions, one uses a heat set insert and the other a nut. 

Required hardware:

Four M5x10 or 12 screws to mount to frame

Two M3x 16 for the clamp

Two M3 heat set inserts or nuts
