I don't have one either, and I haven't done a lot of ABS printing either. I would think it would have a reasonable chance of being ok, since it's mostly empty space. However, since it totally fills the build plate, I wonder if you might have some adhesion/warping problems on the square corners. Depending how even the heat distribution is, the bed might be a bit cooler at the edges, plus you don't have room for brim, or even manually added pads, to help hold the corners down and spread the loads.
To save anyone else having to go get the STL, here's a screen shot of it in Cura:
I wouldn't flip. Printing with the solid covered circle up (open side down) should have less warping issues.
This part is very open which will reduce warping but you will still have some. It's very tough to print something like this with zero brim and still get it to stick. Can you make it 1mm smaller on each side? There is only 1mm to spare right now and you probably need some brim if you want this to stick.
I don't know the answer to your question - it *should* be printable but I don't have much experience with how to get things to stick to glass yet.
I would personally add brim to the cad where it can be - so those square corners should get a brim (like a hat brim) which should be .2mm thick (so only one layer!) and the wider the better, but 5mm should be enough. This helps hold down the corners. Corners have more issues than rounded edges.
