My Intex Adapter for Pool Connectors - Threaded piece

I wanted to make an adapter to do the opposite of this thing:

I have a smaller Intex pool (with 1 1/4" tubing) and wanted to use a larger pump (with 1 1/2" tubing). The adapter above didn't need much in the way of modification (see http://www.thingiverse.com/thing:1625137) but I didn't have any extra of the snap-on threaded pieces. So I made one using the ISO metric thread library.
