Microscope holder

Now I have some idea as to where the microscope goes, I've added a bracket to hold the USB microscope's pole in place on the frame. One less thing I have to screw down to the bench.

I can either swing the mount sideways if it gets in the way of doing things to the print bed, or just pull the whole pole out. Doesn't seem to vibrate when the machine is running. Plan is to make a bracket to hold the microscope I use for watching the initial probe height, then build a base to tuck the electronics in. I'll put the brackets on github when I've made sure the pair don't collide or anything stupid.

I get the feeling I'll need to make a portable package because (a) people are going to want to see Maus at various events, and (b) I want to get this bloody great chunk of plywood off my desk.
