I needed more bag clips since the ones I have grow legs. Had a couple from somewhere (my mom gave them to me) that I liked, so I designed this based on those.

Print at 0.16mm layer height with 3 walls. use normal supports to support the centre and the blocks for the spring, and mouse ears if you have trouble keeping things adhered to your bed.

Uses a 7x19mm compression spring.

The back of the circle will have a single wall which will bend but keep the clip together.
