I got called in early to work, so this is the best I can do until I get back home. The parts are different. The arrows show the hole offset (I will check the exact dimensions when I get home). The circle is how you can tell them apart. The IE version has a 3mm wall there and the other version has a 5mm wall. Please double check this and just double check your tube dimensions while your at it. The last time this happened the wrong parts were printed.
With two of you having issues, I am starting to doubt my geometry... Need to get to the bottom of this. Or I need to get some 25mm tube myself and give it a try.
