Paintball Magazine Spring Winder

thingiverse

You no longer need to rely on pricey store bought springs or cannibalizing your old mags to complete your 3d printed mag projects. With this device you can make your own bespoke, boutique, homegrown springs. USE SAFETY GOGGLES! There is a lot of tension and sharp ends. You will need spring wire, music wire, or piano wire. It is available in stainless steel or regular carbon steel. You can buy it cheaply on AliExpress or Amazon. Read the reviews some listings are not real spring steel. I used 0.6mm wire. Paintballs require very thin wires so they don't get squished. First Strike rounds generally use thicker wire. The internal connectors I used are 1" long 1/4" UNC 20 set screws. The threads can be changed if needed. It can be a little finicky though. you may need to remodel the tolerances if you change the threads. If the outer threads no not line up trim off a few layers of the mandrel by hand with a knife. Or you can add shims of thin cardboard. It is difficult to model the threads perfectly and layer squish can mess up the fit too. You can change all of dimensions for the spring in the Parameters menu. Drastic changes that are too big or too small tend to break the model. Remember that this tool is intended for mag-fed paintball so other springs may be out of it's scope. You can attach the drill chuck end by right clicking the last group in the Fusion360 timeline. You can suppress and unsuppressed the feature. If you have a configuration that works for you share the STLs as a remix or user print file. List the wire size, spring diameter and pitch. As well as the mags you are using the springs in.
