Incontinence tunnel butt plug "anatomically correct" (?)

thingiverse

This is the first piece I modeled myself and the first Thing here. I was tired of the commercial tunnel plugs which are big, long and straight, they lean against the wall of the rectum and block the passage. I did a brief anatomy analysis and drew this model. I believe that the angle of passage and the length of the piece are more anatomical, thus allowing the free passage of material and a real feeling of incontinence. Follow the FreeCAD model if you want to modify it, or you can change the proportions at the time of printing, however, I believe the current dimensions are good. Tell me if it worked well for you. Use at your own risk.
