STL files are available on thingiverse: https://www.thingiverse.com/thing:517...

This is an update from my previous prototype, with many improvements, the main one is that you can now use piano / music wires.
Works with 0.8mm to 1.5mm "normal" steel wires and 0.8 to 1.2mm piano wires.
You'll need a good wire cutter if you're using piano wire.

On the video, i used 25 centimeters (10 inches) of 1.2mm piano wire

This homemade "spring factory" is easy to print (no supports) on your 3d printer. You just need 9 grams (less than 4 meters) of PLA filament.
this tool took less than 80 minutes to print it on my Ender 3 V2.
