About this 3D model

I bought my build plate from the FlashForge web site. It's 1/4" plate glass, which seems a bit thick. I haven't actually printed with it yet, but I will update when I do. My FlashForge has a 75mm wide notch in the back of the Z-Axis mount (behind the worm screw). So I made this one 74mm wide. Fits perfectly (it's red in the photo). Once I get the plate affixed properly I'll do some test runs.
