Curious: Did you get your device 3D printed online? If so, where and what process (assuming laser sintering)? Some of the close-up shots of the cage appear to have pock-marked metal from the sintering process. Am I seeing things? If #2 is correct, did you apply any polishing (unsure if that can be done to titanium). Comfort? Do you have the 3D file (or a form of it) you can post? Any other thoughts about the construction?
