Monoprice Y Axis Motor Mount

My Monoprice arrived with the Y axis motor snapped off in shipping. Getting a new piece of plastic proved slow, and since I had another printer I started working on my own replacement.
I didn't get to putting in the holes for the screws just yet. I was thinking that I should just drill the holes after printing 100% infill, since tolerances on my other printer is a thing I haven't figured out yet.
