*** VERSION 1.2 is available here: https://www.thingiverse.com/thing:5171637 *** *** with this new version, you can now use piano wire in order to make much improved springs *** Instant springs with this 7 grams (0.25 oz) spring factory. Works with 0.5mm to 1.5mm steel wires. 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. I'm currently working on a new reinforced version that would work with spring-steel metals, and produce more efficients springs. Watch the video in order to see how it works : https://youtu.be/LC6OpSbCAPU On the video, i used 25 centimeters (10 inches) of 1.5mm stainless steel wire. Print Instructions: Just print the two things with the classical 0.4 nozzle. There should be no problem with clearance. No need for supports. No need for raft Layer Height= 0.2 (probably works with 0.28 layer height, but i did not try) Use 5 walls, 4 top layers and 4 bottom layers. 20% infill is enough. printed on an ender3 V2, using cheap GST3D PLA filament (8€ / kg). Total cost is around 6 cents with this PLA, and probably a bit more than 10 cents with other brands.. Printing time: Bolt= 20 minutes Screw: 58 minutes at 50mm/s Final spring has a 9mm external diameter. length is about 32mm
