Lendrum-compatible Spinning Wheel Bobbin
by AdanA, published
This is a bobbin sized for use on a Lendrum spinning wheel. It was inspired by / heavily-influenced by / derived from an awesome Majacraft bobbin designed by Krytes42 and test-printed via Shapeways.
I learned of it via the creative and constructive discussion on Ravelry: http://www.ravelry.com/discuss/majacraft-fans/2514814
The 3-part design enables the shaft to be strong along the print layer direction and the endplates to have nice flat surfaces from directly contacting the build platform.
I printed in ABS at 25% fill, 0.20mm layer heights, using a 0.4mm nozzle with no support material. It should print fine despite variation in these values.
Depending on how it prints on your machine, it should either press tightly together and stay, or you may wish to adhere the endplates to the shaft. If you print in ABS, simply adhere with acetone.
Edit, 20151221: previously unmentioned, the concentric rings in the middle of the whorl's octagonal hole are there as a bit of support (not terribly effective, but oh well :-). After printing, bust those out before attempting to assemble around the middle tube.
