Our muncipality recently switched to collection of PMD trash in bags. To prevent them blowing into the street, I made a hook that I can ty-wrap to a lamp post. The rear follows the curvature of the lamp post.
Best printed in something that can withstand the outdoors.. I printed mine in ABS and it's holding up great.
Best printed laying on it's side. No support needed.
Use some beefy zip ties (I used KBUV58013) to fix it to a lamp post and and enjoy :-)
