<p>Anyone have any idea how much power it takes to run a Creality Ender 3 3D printer every day for several hours at a time? Like what does it eat up per hour? A rough estimate of power use per hour would be nice, then I can figure out how much it costs me. Can anyone help me?</p>

If it is really important to you to know how much you are spending per any given print, your best bet is not to guess,
but to know
how much power you're using. To that end, you could purchase a power meter which monitors your power usage. Given the right one, it can even calculate the cost of the power usage all in one little package. This link,
The 10 Best Electricity Usage Monitors
, should provide you some ideas as to what you might find, but I'm sure there are plenty more out there (NOTE: I have no affiliation to the link provided ... it was just a random one I found through a Google search ... Go Go Google-Fu!).
As 0scar pointed out in his comment, there are just too many variables to try and guess what the power consumption
might be
. If you are looking for a real answer, I believe something along the lines as I've linked above is going to be your best solution to getting a real answer. Anything else is more or less just a guess.
