Looks like this has been bent during transport. Or is it with you also so crooked?
Does appear to be bent somewhat. I would recommend removing the mounting plate and place it on a flat surface to see how much it’s really bent. Then probably straighten if you can.
Ok thanks, i think i get it. Just want to be safe that is not the correct form.
It really depends on how well the laser/mirrors are aligned there…although that looks pretty extreme.
oh jeah it is BENted 
I uploaded a Video for you. I will screw it between two heavy and plane parts I found.
Now that is my planed fix
Its better then before.
But not really plane. I searched on thingiverse but did not find a replacement sketch for my 3d printer. Whatever, I will give it a try.
I found this on thingiverse that looks like it could work. https://www.thingiverse.com/thing:621265
Cool, thanks.
And last but not least a BENted fixed photo

I rebuilt my objective stage using .22" acrylic and have been happy with it.
