summary
simple usermod for Hero Me Gen 7 enabled Ender 3.
original Hero Me Gen 7 files only support BLV Ender 3, which converts all axis to linear rails and uses CNC parts and i didn't like it.
so i designed a dedicated carriage/gantry for stock Ender 3.
you can now attach MGN12H rail on top of your X axis.
BOM
MGN12H 300mm rail x1
you do not need to buy carriage separately. it will come with rail if not specified.
i highly recommend RDBB's rail. original Hiwin rails are probably overkill for Enders.
M3 Hammerhead Nuts x6
you can use T-nuts instead.
M3 6mm SHCS x6
for locking rails.
M3 30mm BHCS or SHCS x4
for assembling printed parts together.
M3 OD 4.5 L 4.5 Threaded Insert x4
insert them in front plate.
print settings
use PETG at least. PLA won't endure temperature.
40% infill, 4 walls, 5 bottom and top layers.
downsides
it is not rigid enough due to top rail mount.
