Instant springs with this 9 grams (0.30 oz) spring factory.Works with 0.8mm to 1.5mm "normal" steel wires and 0.8 to 1.2mm piano wires. This is an update from my previous Spring Factory (https://www.thingiverse.com/thing:5142754), with many improvements, the main one is that you can now use 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 wireThe "spring factory" is easy to print (no supports) on you 3d printer. You just need 9 grams (less than 4 meters) of PLA filament.It took less than 80 minutes to print it on my Ender 3 V2. Watch the video in order to see how it works : https://youtu.be/QOz2l867N_4 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 raftLayer 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 Cap: 3 minutes Final spring has a 9mm external diameter. length is about 32mm List of improvements (version 1.2):Both parts are easy to handleAble to handle 1.2mm piano wireA cap is provided in order to put the spring on a flat surface (watch the video)The wire can be locked with a simple systemI've added some length to the screw, so you can make longer springs.
