The original didn't fit on my Ender 2 Pro. I have made the left and right able to fit around the gantry bolts when mounted. I also widened the holes where the inserts go in to make it easier to set the inserts in with a soldering iron. I'm only using one bolt on the left side where there are 2 right next to each other because the bottom one didn't line up. Only using the one has been fine.
The author remixed this model.
