Thx to grant for original upload … mine snapped after a month or so though so I made a slightly beefier variation …
See attached photo for ref - added 1-2mm on shoulder and round catch (green is new variation).
NB - Just printed / installed this so I can't say yet whether this improved anything ;)
UPDATE 01 Oct 24 - Made a thicker version cos someone managed to snap this again :/
The author remixed this model.
thicker female versions - original broke too easily
