BLV mgn12 (Jig) AM8 ultra mega cube y-axis jigifier

This is an extremely high tech and over-engineered jig for the BLV mgn12 mod. Using advanced maths and sciences, I concocted a technological marvel consisting of the following features:

1. 39mm wide to align your y-axis rails the appropriate distance
2. 51.5mm long to center your y-axis belt tensioner
3. 26.3mm tall to get your y-axis motor mount juuuuuust right
