This is an Ender 3 Pro to Standard Ender 3 remix of the PSU relocation mount that was created by ProperPrinting to make room for his Dual Z axis mod.
The main casing was modified to accommodate the larger PSU of the standard Ender 3 and the Y-axis bracket was modified to fit the 2040 extrusion as opposed to the 4040 of the Ender 3 pro.
As with the original design, you will need to use These side T-slot nuts as designed by ProperPrinting.
Included are both the "with and without vents" variants.
I've had good success with this filament at 240c nozzle and 75c bed.
