Printed
@phunguss shroud, thanks for sharing!. Having spent much time reading and experimenting I finally have a near level print bed to work from, thank you tiny pieces of square paper!. The shroud served as a good test for what I should and shouldn't be doing while the print is in progress, like you shouldn't be pushing down on the sides to try and fix it to the base, just put more glue down!. The support structure is an amazing object in itself, 3D printing is awesome!.
I don't know exactly how your bed is leveled but I converted mine to a 3 point level instead of 4 and it's much easier to level.
