Ivan Owen sent me this version of Bob Roth's latest update to his finger design. Ivan optimized it so it doesn't require supports as he created a couple supports in the original stl that you can just tear away after printing. All of the pieces printed beautifully except for the back knuckle piece as it was lifting off the bed. This is good enough that I can test and I'll print a new one later. I uploaded the Ivan's adjusted files to Thingiverse.
