DYI 3D printed GT2 Kit for autofocus Sky-Watcher Evoguide 50ED with ZWO EAF electronic focuser. You will also need a GT2 6mm width 260mm length timing belt and a 2GT timing pulley with 5mm bore, 6mm wide and 12 or more teeth for the ZWO EAF shaft. The bracket is fixed to the camera side end of the focuser because this part will be at a fix distance to the green focuser ring. The telescope end of the focuser is moving relative to the focuser ring and the timing belt will move if you fix the electronic focuser to the telescope body. The fixing is done with the 3 screws already existing on the telescope. ZWO EAF come with 2 M4 screw for fixing. It is intended to work with Sky-Watcher Evoguide 50ED dedicated flattener. I suppose it can work with Starizona flattener as is or with small adjustment.
