Spring Pins & Snake Pins
by PrettySmallThings, published
Flexible pin connector segments to work with tbuser's Toy Robot Toolkit. I created these in my marionette quest, and while useless for my marionette, they might be useful in a myriad of other applications.
Neither of these designs is a direct derivative of Zomboe's, Landru's or Emmett's work - but they are certainly inspired - so I'm spreading the derivative love all around.
If you're working with solid modeling, you'll find a rebuilt, solid version of tbuser's basic pin & hole negative buried in the CAD file.
Print your favorite pin. Both varieties are fairly stable in ABS, but aren't indestructible.
