The first one I broke when taking the supports out, glued it back together but printed another with thicker bars and thicker walls. Then, I actually got a lock, so I could design it in. That’s when I changed to the purple. With the redesigned interface between the ring and the cage I could print it upright without support so I didn’t need it to be quite as strong so I lowered the tube size again. Then the lock housing broke because it was then and turning the key levered it against the strap wing to put upward pressure on the lock. So, I increased the lock housing strength and removed the strap wings, at least for now. The ring ended up breaking again because I accidentally printed it with no infill, just thick walls, so the base of the lock housing was deceptively weak. No design change for that one, just reprinted in the sparkly black with 100% infill. Then, I stumbled onto the form tool in fusion 360, which let me make the design a lot more flowy and organic looking, and that’s the current version.
I mean to add that back to the ring at some point but it’s a bit beyond my technical skills to do it in a good, smaller way that won’t interfere with the key
The previously broken one!
All the previous iterations

I love the curvy shape of the two in the.middle.
