Component Test Adapter

thingiverse

For years, I resorted to various methods like alligator clips, paperclips, and even gripping components with my fingers when testing two-lead devices such as thermistors, resistors, capacitors, and sensors. However, enough was enough – it was time for a sleek solution! Introducing a quick and easy-to-build clip that securely holds test probes for measuring two-lead components. I used readily available parts like red and black pin jacks (e.g., Pomona 3542-0, -2), a Molex shell (08-65-0816), Molex terminals (08-65-0816), along with wire and a 3D printed case designed using a Replicator 2 with specific settings. To assemble the clip, drill hexagonal holes to 1/4" and ensure a snug fit for the Molex housing. Solder wires to the pin jacks, crimp Molex terminals onto the other ends, and press them into the Molex housing. Finally, attach the bottom onto the box, guiding the wires into the terminal support slots. Trust me; you'll wonder why you didn't do this sooner!
