About this 3D model

For years I've been testing two-lead components using alligator clips, paperclips, gripping them with my fingers to the test probes, etc.... ENOUGH!!! Here's a slick little build that you can quickly clip your test probes into when measuring two-lead components (I'm usually measuring thermistor output, resistors, testing capacitors, sensors, etc.). I had all the parts on hand but nothing is too expensive or hard to get. I've included a bill of materials....
