SummaryThe little snap-on connector for the strap on my son's Crocs broke. 5 minutes in openscad, 7 minutes on the T-O-M and it's fixed! Hopefully it will be durable enough. I resisted the urge to make it snap together, it's designed to be glued. I also resisted the urge to add some fancy logo to it. Feel free to do so.InstructionsPrint it. Clean it up so that they fit together. I smeared it with a little acetone/ABS slurry in the hope that it would penetrate and make the layers adhere a little better. Stick the large side in the strap, stick the little side through from inside the shoe and glue them together (I just used the acetone slurry, CA would probably work just as well).
