Jump wire maker 7.5/10 mm

thingiverse

I bought a jumper wire set to do electronic work using a breadboard but only 7.5 mm and 10 mm decreases were needed. It was a waste to purchase additional for that alone, so I made it myself, which turned out to be quite a big deal since measuring lengths one by one was tedious. So when making this tool, I got a little easier. 1. Prepare AWG 22 (0.65 mm) vinyl-coated single wire. 2. Cut the wire to about 17 cm for 7.5 mm and about 19 cm for 10 mm. 3. Pull off the covering with radio pliers or similar tools, carefully separating it from the core wire without breaking it since vinyl covering is fragile. 4. Locate the groove with one side open at both top and bottom of a scalpel. Place the core wire in the long groove and cut it into 8 equal parts using nipper etc. 5. Put the vinyl covering on the shorter groove and cut out 8 pieces, discarding the rest. 6. Place the vinyl covering in the center of the cut core wire. 7. Arrange six pieces of vinyl-covered core wire in grooves lined up for four tools, adding a male connector to complete the jumper wire.
