Got the Fidlocks in, tried the Slide and V-lock, went Slide. Tore open the prototype, measured and rounded up my sizes and then sewed up a final one. Not my best sewing but I’m not used to seeing loops this tight. My only regret is how I looped the long end of the buckle as it feels “upside down” when grabbing it blind but otherwise it went together well, fits the same and the buckle rocks. Same printed PETG parts as before and they’re holding up really well, too.

The real life saver here was remembering to do test prints while designing. The first test didn’t fit at all and I realized only 20 minutes of CAD in that I’d grabbed the wrong base profile: the default Dactyl-Manuform instead of my modified one. I also found it got in the way of my rubber feet. I also leveraged Fusion’s variables and joints heavily so I could tweak what I call “tilt” and “rotation”, which are realized using these two blocks that are not exported with the rest of the design.
