NOTE on proposed change: Alex is not happy with a design decision. His plan is to move the fiber hole to the "front left" of the box, positive delta z negative delta y to increase bending radius. Maybe it is actually maximized by only a delta z change. The downside is that FEEs are no longer independent. If we want to remove FEE1 will will need to disconnect all SiPM connections (1-11) first. The advantage is that it is simpler and bending radii are larger. Only two orange ball mounting points are used then (at the box entrance and just before a fiber-SiPM connection).

This is a schematic for the current design of the FEE box. This FEE box is not totally symmetric, so this is the one at say 3 O'clock on the east side of STAR. The first three pictures show:
- FEE box (yellow) with transparent top (for pictures) and no front. Front (perp to STAR "z", pulls away from magnet along z) is removable. Top may or may not be removable/hinged. This should be made of 1/16'' Al, bent into shape.
- 3 simple grey rectangular rails for supporting fibers, just ignore these.
- The card cage assembly (grey backplane + grey rails). Includes small grey spacer block to make rails holding FEEs uneven in z. This makes it possible to pack them tighter.
- EPD FEEs (blue) with magenta female end of card edge connector.
- attached to FEEs via card edge connector is SiPM board assembly consisting of SiPM board (green), spacer block (blue), and fiber-SiPM connector (red). Most detail here cannot really be seen.
- Green example fiber running through the hole in the FEE box down to a given fiber-SiPM connector. I think this is basically reasonable. It is ~75cm long.
- Orange balls denote location of some sort of fiber clamping, they are not going to physically be there. Probably these are just zip-tie locations. Maybe there will be a few more.

Picture 3 is the card cage alone. Pictures 4 and 5 are the box alone with dimensions.

There is also an attached picture "FEE assembly exploded.PNG". The FEE board depicted here is of an older kind but the picture is attached to show the SiPM board, the spacer block, and the fiber-SiPM connector.

Caveats:
- Fiber support not totally finished.
- Fiber hole in box side will be slightly increased.
- Holes needed for signal out and power in in box
- Power to FEEs may be accomplished via simple backplane. This is not designed nor depicted
- Box is missing a few screw holes
