I need to join these two parts, and I can't think of a way to do it that will keep it strong, since there will be forces put on it, in the direction of the arrows. If it helps any, the print raises the monitor higher than where it would normally be. So instead of the arm connecting to the middle of the monitor, it connects closer to the bottom. And the reason for the force is that I often have to change the tilt of the monitor when switching from sitting to standing (I have a sit/stand desk)
If anyone could help, it would be greatly appreciated.
