About this 3D model
This is a clip mount for 35 mm DIN rail. http://en.wikipedia.org/wiki/DIN_rail I had a relay for a radio that was already DIN rail and I needed to mount some plugs and cables. http://www.flickr.com/photos/zignig/sets/72157621190394069/ So I fired up blender and Modeled a DIN clip. TIP: Getting the sizing just right on a reprap is a bit tricky , so I printed out thin ones ( ~= 5 layers ) to get the size just so. I used this for a ham radio that I have mounted in my car. :) zignig
