Phoenix v2 Hand



Profile picture of Andrew Schultz

Hey everyone, my Name is Andrew Schultz and I am from the E-Nable Cincinnati Manufacturers Chapter. I have had a couple issues in the past and with my most recent build of the Phoenix V2. Issue #1: When the recipient of my most recent Phoenix V2 hand used her new hand for a consistent amount of time, she found that the wrist pins were popping off. Resoution: I added small locking tabs that pushed between the clipping features of the pins after they go through the wrist pin cap. This makes it so they can no longer deflect on are quite litterally locked into the wrist pin caps. So far, this has been a 100% successful modification. ![wrist pin.jpg](file-guid:5a76fde3-3b97-4732-b3b2-0558c90683fa "wrist pin.jpg") Issue #2: The little girl is using a socket and I had to modify the palm to accept the silicone socket provided by RJ Rosenberg here in Cincinnati. thumb would help provide opposite gripping from the radial side, but things would slip a bit on the ulnar side grip. Resolution: I removed the mesh from the underside of the palm and modified the design to include a positive palm pad. ![Screenshot 2022-05-18 224206.jpg](file-guid:5003c165-bb3c-4e98-b9d1-9b50019cf512 "Screenshot 2022-05-18 224206.jpg") Issue #3: When printing my new palm (which was heavily modified), I had trouble with support material trying to print inside the ligament tunnels in the palm. It was nearly impossible to clear out those tunnels. Resolution: I decided to redesign the tunnels using a teardrop cross section with a 60° angle at the top of the cross section. This worked perfectly. \ ![Screenshot 2022-05-18 224121.jpg](file-guid:c0750f10-8e64-4a7c-beb6-1aca5bed2013 "Screenshot 2022-05-18 224121.jpg")
