chain bracelet snap fit , with extension link - very comfortable

To start, I love this print, it's designed functionally minimalistic, industrial, cute, to say the least... I could never get the hook to not "break off", so since I like this model so much, I did what I needed to for the chain to be secured together without fear of snapping the "weakest link."

printed with 100% infill, or simply use 6 bottom and 6 top layers if 100% infill still doesn't make this completely solid.

I have successfully resized this to be flatter or less wide with acceptable results.
This model is not completely solid, but it is solid enough that you should use the extensive stitching option within Cura to remedy this.

This is very comfortable to wear.

Note: there is a round profiled bar that links these together, so if you change the length without compensating for the height, then the bar becomes oval, which impedes the angle that each chain link is free to move.
** If this imports odd-sized, I would measure the circumference of the wrist you wish to fit this to and set that as the overall length, plus a few more mm for fit. The width is somewhere near 15mm, but YMMV
