About this 3D model

The Atom extruder which is bowden type connect through the hole to the upper right corner of aluminum frame with bolt setting at a appropriate angle. It seems to have an angle of about 45 degrees usually. On the opposite side of the hole, plastic parts of z-end is installed. The z-end is designed having two holes to bolt the aluminum frame side, but in order to tighten the extruder, the z-end hole of the right side bolted from another side. However, since the extruder is fixed only by one point in spite of heavy enough, the angle is not settle completely. In addition, the results in this angle is changed, the bolts that come loose. Therefore, I modified the z-end for set the angle. Aluminum frame is assumed to be 5mm.
