Rectangle prints as parallelogram

HI all,

I printed a battery holder for a micro-quadcopter yesterday.

In essence it is a rectangle flat plate, with two slots in the base, then some built up sides. Very much like this (I can't find the original thingiverse page now) https://www.thingiverse.com/thing:2798064

The print looks fantastic, no stringing, perfect holes etc.

However, the overall print is not "square". i.e. it's more like a parallelogram when looking from the top or bottom. I printed it with the long edge along the X-axis.

I've not noticed this before, but it's also rare I print anything so uniform in shape….what could cause that?

The G32 routine run in the start code had a resulting deviation of 0.038 by the way.

Printer is Tevo LM adapted with duet wifi board and smart effector.
