Sony MZ-N920 Case

This is a case I designed for my Sony MZ-N920 in Fusion 360. 

There are several variants of the design, depending on if you want to attach the case with screws (using existing screw holes) and if you want a cutout on the front for the logos. To attach with screws, you will need 4x M1.4x4 screws for the upper and 1x M2x4 flat head screw for the lower. There are also versions with and without support geometry for the cutouts, since TPU does not really work with traditional auto-generated supports.

If you print in TPU, and want to attach it with screws, there are a few extra steps. The file (file name here) has divots on the outside surfaces where you can drill and then counter sink for the screws. This requires some extra tools: a #53 drill bit, and countersink deburring tool, both as sharp as possible. You will need to freeze the part (with a can of electronics duster) to drill and cut it. I have found the results with this method are significantly better than trying to print the finished geometry, as the holes disrupt the inside perimeters and cause artifacts.

(Note: I have only included a profile for PLA, if you want to print TPU, you should fine tune your settings to the specific filament.)
