Bobbin For Spinning Wheel With 110mm Length, 6.75mm rod like Ashford Kiwi 2

thingiverse

I'm creating an eSpinner while also testing my Bobbin design along the way. The idea here is that I can make different end caps with a very good fit for each shaft size. First, I'm uploading a 6.75mm shaft size that works with an Ashford Kiwi spinning wheel. So print two adapters, one for each end, and then just one of each other part. You need to glue one side of the bobbin on after printing because it was easiest for me. The end caps that can adapt the shaft size seem to stay in place okay on their own. There's a chance if you don't do a super job gluing it that you get a tiny wiggle, but in our case, it wasn't enough to cause any issues since the whirl on this spinning wheel has a more obvious wiggle.
