Instant springs with this 7 grams (0.25 oz) spring factory.
STL files are available on thingiverse: https://www.thingiverse.com/thing:514...

Works with 0.5mm to 1.5mm steel wires.
Currently this machine does not have the capacity to make real spring-steel springs, which limits the mechanical characteristics of the spring obtained. But if your load is low, these springs can help you out. Everything will depend on the material you're using.
Therefore, I'm working on a V2.0 which is able to deal with piano wires. I'll update the project on thingiverse as soon as all the tests are OK. Currently, it adds one gram to the machine.

On the video, i used 25 centimeters (10 inches) of 1.5mm stainless steel wire.

The "spring factory" is easy to print (no supports) on you 3d printer. You just need 7 grams (less than 3 meters) of PLA filament.
It took less than 80 minutes to print it on my Ender 3 V2.
