Spinolution bobbin for Echo (4oz) and Mach III (8oz)

thingiverse

This spinning wheel bobbin was designed for the SpinOlution spinning wheel. This is an easy print. You will need to turn on supports to get a good print. The project comes out fairly clean, with only a little cleanup on the supports. I have include files for the 4oz bobbins, and the 8oz bobbins. The 4oz bobbins fit all of the Spinolution machines that have 4oz flyers. The 8oz bobbins will only fit those machines that do not have the golden whorl. If your machine has the 9mm shaft, these will not work. Both bobbins are assembled the same way. To turn this into a complete bobbin for your wheel, you will need to get a small M8 washer, and a piece of 1/2" PEX, CPVC, or copper pipe.

For the 8oz bobbin, the pipe should be cut to 144mm. If you don't already have a pipe cutter, I highly recommend getting one. You can complete this project without one, but it sure makes it easier. I use this one: https://www.homedepot.com/p/HDX-Junior-Tube-Cutter-HDX003/204218579 After printing the 4oz_1, or 8oz_1 file, insert the washer into the round end. Then insert the plumbing pipe into the hole on top of the washer. Press down on it hard to get the washer all the way seated. It's a tight fit, but it is possible. Pull the tube out and glue it. I just use plain old super glue with mine. Once you have press fitted the top piece, test it to make sure it will fit your spinning wheel. When you feel good about everything, glue the top piece to the tube. If you find this useful, please let me know in the comments.
