PCB image not correctly cropped

[agners]

I've come accross an issue where the PCB wasn't properly cropped. There was a lot of white space on the left and underneath the PCB. On the lower left there was also an axis arrow visible.

It turns out that this axis arrow was the culprit. Disabling it in the KiCad default settings in /usr/lib/python3.10/site-packages/pcbdraw/resources/defaultKiCadSettings/3d_viewer.json by setting "show_axis": false helped.
