This is a remixed version of the awesome print in place iris box made by LoboCNC. After seeing the amazing looking westworld control unit housing done by ThaRev (https://www.thingiverse.com/thing:2984003), I decided it just wouldn't be complete without a functioning Iris box for the top. Thanks to the solidworks file provided by LoboCNC I was able to aesthetically alter his iris box to look like the control unit and to have it be perfectly usable with the rest of ThaRev's original files. Simply download ThaRev's files and print this instead of his supplied "Westworld Control Unit Upper".
NOTE You may need to slightly scale down the diameter and length of the pins he supplies
I also bumped up some clearances to allow a wider range of printers to be able to handle the print successfully, see print settings for detailed instructions.
