Edit: I came across this thing after I created mine: https://www.thingiverse.com/thing:1641044
I just printed it, and honestly I think it's a better option than this one.
MonoPrice Maker Select V2 aka Wanhao Duplicator i3 V2 printers have an issue where a cable can get hooked on the back of the frame.
This print snaps onto the frame and forces the cable up, so it can't catch on the side of the frame.
If you print without supports, it's pretty forgiving. The supports are in the large gap that holds the cable, so it can be cleaned up easily with an Exacto knife.
The fit is a little tight, so I recommend hooking the bottom lip first, then, while trying to clip the top, press down on the top to get the needed clearance.
