Designed this cute dog poo bag holder to keep my hands free when walking my dog. Clips on to most standard leashes and holds one or two bags if necessary (assuming they are knotted).

Use the tail of the snake for most bags and the mouth for thin bags if they are able to escape the tail holder.

I printed with 30% infill and 2 walls on the Bambu P1P with Basic PLA and struggled to deform it manually. Hopefully this means it is sturdy enough for everyday use.
