xy size compensation for EM 2 pro

[cliffyk]

OK, the destructive test:

I clamped it rather firmly into my small bench vise ("upside down" at the third step):


Then whacked it (one good sharp blow) with a 16 oz. ball peen:


It held up pretty good for a 3-D printed thingy (you can see the indentations from the vise jaw):


Again, a 50/50mix of Tenacious and some cheap gray crap.

Seems like good mix, now I need to print some sort of real component...
