The mod you can find at mod portal: https://mods.factorio.com/mods/darkfrei/Shift_Tool
This is a mod, that says what the shift are you need. This toll you are need when you make your own graphics with shadows, but your graphics is not in the middle of the collision box.
For example:
Entity
type = "assembling-machine",
name = "assembling-machine-3",
Code: Select all
animation =
{
filename = "__base__/graphics/entity/assembling-machine-3/assembling-machine-3.png",
priority = "high",
width = 142,
height = 113,
frame_count = 32,
line_length = 8,
shift = {0.84, -0.09}
},How to use this tool
Place your entity somewhere 
Find collision box
Make one Shift Tool
R - for rotate, place image of the entity to the center of collision box
Press F5 for debug net
For example here is the right position
Last message have right position for your entity, write it to the mod
