The two parts should be separated in the slicer such that the outer case can be printed upside down. This reduces support requirements greatly. This is a moderate print with some fine details, support is required. Support removal is not difficult but care should be taken not to over stress that parts as it is removed. After printing the sliding surfaces should be sanded slightly to remove roughness; that is the slide slots inside the outer case and the rails at the edges of the interior piece. The puck holder should also be sanded to that the puck fits easily inside the holder. If the puck is too tight the holder will crack. Finally, the cable guide at the bottom rear is very tight and some adjustment to it will probably be required. None of this is difficult but will ensure smooth operation.
