Y-Axis tensioner for HICTOP Prusa I3 3D Desktop Printer

This is an improved Y-axis belt bearing holder and tensioner that fits into the original place on HICTOP Prusa I3 3D Desktop Printer. The piece is hold in place via a single hex-bolt (4mm) and tightened via a butterfly nut. This requires drilling a hole - at the center of the plane formed by the existing four square holes on the y-axis end-piece. You will understand what to do, once you place the part in place.
