Recently a strap clip on a bag I got broke. I decided to quickly design one and replace it.
This is a lasercut version of a strap clip having a sigmoid (capital sigma) shape. The shape prevents the clip from rotating under load.
Take care: the corners can be quite sharp.
I tried an open design first but that proved to not be mechanically stable enough to carry weight.
Lasercut the .dxf file then sew it in.
