I printed these on my Bambu Lab CX1 on Fine detail 0.12 mm layer height on the “silent” slow setting Hatchbox Glow PLA . They turned out great.
I took some small paracord inner rope to make the small lanyard bit and some regular orange 550 for the strap. Fuse the ends and pull them through the lanyard bead and then fish the adjuster bead into the back of the strap.
