One of the easiest things to print in flexible filament is a wristband. This one however is tricky because of the embossed lightning bolts. I printed these in 2 different flexible filaments. The lower the "shore hardness" the stretchier they are. I printed the pink Ninjaflex one (SH = 85A) and could stretch it over my foot to wear it as an ankle bracelet. The red, white and blue ones were printed in Cheetah (SH = 95A) and although they were super easy to print and they aren't as flexible. I couldn't stretch the medium one over my hand or the large one over my ankle. The small is for little kids. I commissioned this design from Z. Frew. This is one of my favorite bands.
