4 Pole Measuring Aligator Clip for Milliohm Meter with seperate Current and Voltage Path

thingiverse

This is a groundbreaking debut of my 4-pole milliohm meter test clamp. To accurately measure small resistance values, it's essential to keep the current and voltage paths distinct. That's why I've designed this clip with four poles, ensuring precision in every measurement. While the clip can accommodate up to four poles per piece, I anticipate using two pairs of clips for axial components most often. The clip is specifically tailored for 20mm long, 7.5mm diameter extruder springs like those available in my eBay store (https://www.ebay.de/itm/183819685405). Note that you can use two identical versions of each design (2 or 3), but the version 2 components alone require a spring longer than 20mm for a secure grip. Using a pair of version 3 clamps is necessary to achieve a tight grip with the springs I offer. Assembly requires an M3 20mm screw and M3 nut for each clamp, or alternatively, a piece of 3mm filament can be used. These clamps will be integral components in my open-source component tester (https://github.com/usertogo/NanoBatteryTester001), which aims to evaluate and categorize various parts, including batteries, fuses, diodes, solar cells, and more, for solar electromobility applications.
