Stencil - download the kicad files, export gerbers and upload to OSHStencils.
A reflow skillet
A test rig - if you want to test the result without soldering.
handy guide for how to put everything together. Note that the markings on the board are not great for locating where to put the components, so I recommend printing out a component map and the list above, then cross things off as you go.

Reduced number of different components by two.
Better stencil (might still need improvement though)
