X-axis is not perpendicular to Y-axis

The X-axis is not perpendicular to the Y-axis on an ultimaker 3 (more than 1° off: see attached picture). Is there a way to fix this?

Are you sure that it's not just the plastic that has moved? Removing the part when it's still warm makes it easy to bend it. Another thing that can happen is that once the parts comes off the glass and cools, the plastic can move a little bit. The reason I ask is because the part looks more bent than printed at an angle since there's a curve to it.

 

But to align the axes you can follow this guide:
https://support.ultimaker.com/hc/en-us/articles/360017142879-How-to-align-the-axles-on-your-Ultimaker-printer

 

Or this one that I wrote years ago which is the lazy way of doing it without the calibration sticks:

Thanks for the guides.

 

(Plastic has not moved. I printed this L-shape to demonstrate the angle. I  see this in all other prints but I printed this shape to demonstrate what is wrong. The curve seems to be a consequence of a cheap cell phone camera.)

 

I will try to align axes with the first guide since visually, nothing seems wrong (bit difficult to eyeball a 88° or 92° degree angle) . I am now printing the calibration sticks. I do not have a torque screwdriver. Is this a problem?

Real late reply here, sorry. But no, a torque driver isn't necessary. Just make sure the screws are nice and tight when you're done.
