Primo - Lower Belt vs Mirrored - Difference?

I printed all my parts, but haven’t labeled them yet. I am going through all of the parts and came across the Lower Belt and the Lower Belt Mirrored, but I cannot tell the difference? Are they exactly the same? I have 4 printed, 2 are one and two are the other, but I’m not sure which is which. Any advice? Thank you in advance!

They are very similar, but they are not identical. I brought both into Fusion 360, and this is the image when they are superimposed:

You can see where the position of the slot and loop are different, and a closer inspection might show other differences.

Edit: Now that you know the slot is different, here is the image of the normal (non-mirrored) one shown from the side with the open slot. You can hold up your parts and compare.

Incredible response time and detail to my question! Thank you so much! I visually cannot even see the difference if i hold them up next to each other…I will take my chances guessing, but if it doesn’t fit right i will just re-print these parts and label from the beginning so I don’t get them wrong. Thank you again and have a great day!

Here is a 3D shaded view of the normal (non-mirrored) one:

Note how the slot at the top rolls over the right edge, and how the slot is noticeably closer to the right edge. If all four of yours look the same, then you probably printed four of the same version.
