Parametric Hook with a compliant loop to hang items from a Rail.

The attached File is for a 25 mm rail however the parametric Onshape model can be modified by changing the values within the variables folder:

Clearance between the mating parts may need to be tweaked depending on your printer tolerences.

Despite the thin material, the compliant loop is stronger than the hook, I suppose the whole loop is redundant really if the desingn is only as weak as the hook.
