Power coupler for a Shopsmith for my friend Rich the Engineer.

While not a remix of [Krunchys model](http://www.thingiverse.com/thing:147773/) it certainly was inspired by it.

Just like Krunchy says, use at your own risk. I have no idea if it is fit for your use, how long it might last, or whether it will break into 73 pieces, put your eyes out and kill your dog.

The printed part is a tight fit, and a few of the teeth, were shaved during installation.

Rich hooked this low fill (5%) POC test up, and tried it with a light load. It worked fine.

The next test is an ABS print with 8 shells and 50% fill.
(The resulting stl file would not convert to xg3 for my flash card)

If you make one, or have problems with it, I would love to hear about it.

I ended up getting some Filabot 910175 Taulman 910 Alloy filament.
It took a lot of tries to get things working right.
The real key is 255/65 temps, and slower speed.
It seemed to work best with 2 shells and a 50% fill.
