This is a remix of Afterschnitzel's bed corner locators for a Ratrig V-core 3. I'm using them with my 400x400 but I assume they'll also work for the 300 & 500 versions.
It moves the mag sheet forward so it's inline with the inside edge of the countersunk holes making the tang sit over the front edge of the bed just enough to easily remove it.
You'll need a pair so just mirror it in your slicer. You'll also want to print one of these:

so that you can adjust your Y endstop forward a touch.
edit: I was asked to add the step file so I have (and the f3d version). It's not the cleanest as I tweaked the original mesh bit it works.
