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.
3 bottoms layers
4 top layers
NOTE You may need to slightly scale down the diameter and length of the pins supplied in ThaRev's original files.
YES THAT GAP IS SUPPOSED TO BE IN THE MIDDLE OF THE PART
It is designed to still print without supports and is required for the part to function correctly.
I may release a future version that hides the seam better.
You may need to tell your slicer a line width of .39 for the thinner features to be printed correctly.
If your printer suffers from stringing you will HAVE to reduce this via retraction and temp settings prior to attempting this print.
Freeing the Pedals
Once printed, you will need to free the pedals.
First, cut the 8 tabs (2 tabs/pedal) on the bottom of the part as shown in the pictures.
Second, free the bottom section by carefully prying between the small seam between the upper and lower shells. Run a flathead screwdriver or scraper along that seam and you should hear a slight cracking sounds as you free the bottom half.
Next, you may need to free the top pivot of the pedals. There is a pivot pin in the top left corner of each pedal, as shown in pictures above. gently slip a screwdriver between the pedal and the inner shell and pry until you hear a slight crack showing the pedal is free to rotate around that pivot.
Lastly, You may need to run an xacto knife between the pedals and the inner and outer shells on both the top and bottom of the pedals. Do so very careful, it will not take much force to free any stray strands.
Tabs to cut on all the pedals
Pry at this location to free the bottom shell
these are the pins that the pedals need to be able to rotate freely around.
