Spinolution Bobbin for golden whorl flyers
thingiverse
Ends for an 8oz Spinolution bobbin to fit the newer wheels with golden or 3D printed whorls. I used <b>crazyhoratio's</b> design https://www.thingiverse.com/thing:4314245 for the twelve point cutout to match Spinolution's wood bobbins. The bigger bobbin has an inset on one side for a metal spacer.(https://www.gobilda.com/12mm-id-steel-spacer-15mm-od-2mm-length-4-pack/) It's sized for 1/2" CTS CPVC pipe. (PVC would work fine, but you might need to double check the inner/outer dimensions.) I still have a couple tweaks I'd like to make, but the current version is working happily so far!
