I used a community members model as a starting point and developed a little further. I tried to retain most of the original design intent as possible while applying DFM design techniques to the widget.
Designed in Solidworks
The author remixed this model.
There was some odd geometry in the mesh file of the shell which I repaired and the peg did not seat all the way into the core so I lengthened it. I also adjusted the geometry so there should be no need for supports (inner lip of shell) that do not “touch platform”
