Dupont Probe Adapters for PCB Workstation

thingiverse

Many hobbyists such as myself always have a few spare male Dupont style jumper cables in their toolbox, just waiting to be turned into articulating probes for a DMM or scope. My design is a remix based on Giufini's Octo+ PCB Workstation thing:\r\n\r\nhttps://www.thingiverse.com/thing:2427726\r\n\r\nTo assemble the probe, first remove the plastic connector housing from your connector. Next, slip as many ball/sockets as needed over the wire, snapping them together one by one. When the arm is complete, fish the wire through the probe tip, reinstall the plastic connector housing, then push the connector back into the square hole until it is seated firmly against the stop. To finish it off nicely, use wire cutters to snip the tips of the probes at a sharp angle, forming a needle point.\r\n\r\nI printed with ABS at 0.1mm resolution because I like how smooth the ball/sockets come out (it feels like they move better than ones printed at 0.2mm). The square hole fits snugly with my printer; if your printer has issues with tolerances, you may need to scale up x and y for the connector to fit in the tip. If you do scale up and the socket becomes too loose, you can fix it by adding thin heatshrink (or glue, or tape) to the last ball on the arm where the probe snaps on.
