PS3 4x Nav Controller holder

The Playstation 3 Move Navigation Controller is a wand-style bluetooth game controller that is essentially half of a standard PS3 SIXAXIS.

As it is bluetooth, it can be used for purposes beyond gaming (such as remote control of arduino robots). I have several controllers for such projects, and wanted a better method of storing them than a random box when not in use. I designed this thing to slip over the edge of the hutch on my desk (~ 16.5 mm thick wood). Each holder has space for four of the controllers.

The parts needed to assemble one holder:

* One Controller Mount print
* Two Desk Mount prints
* Two machine screws, M3 x 10mm or longer (within reason)
* Two [M3 brass heat set inserts](https://www.amazon.com/dp/B01IYWTCWW/ref=cm_sw_su_dp) (4mm outer diameter x 3mm depth). I already had these inserts on hand so I designed this around them for strength. They are heated with a soldering iron and melt their way down into the part as they are inserted.
