Summary

not a remix of this one, but close.
i can never find the original, and the original i used for a long time used filets, which always made the edges funky.

so this uses chamfers to make the edges look a little better, it also has a slightly rounded point where the bag enters the track.

i like to print mine with concentric infill to give more strength. depending on the carabiner you use, might want to unlock settings in slicer and drop z just a tiny bit so it fits better in the carabiner.
