About this 3D model
This is for squarin up your rails when you tension your x & y belts on the Ralcore. Use this to make sure you are not pulling harder on one end than the other causing it to be out of square. As a side note: This part will need to be made on a machine that is already square. If you do not have that option this print can be scaled down if desired and printed to be checked with a square to check for printer squareness.
