Double-width spacer bar for the Fallout 3 / New Vegas Pip-Boy 3000 replica

Ideally this should be printed with Multi-Jet Fusion (MJS) or Selective Laser Sintering (SLS), but a good-enough print can be made with a home Fused Deposition Modeling (FDM) printer  in PLA or ABS. For FDM printing, the part is probably best oriented with the large hook feature at the top, as shown in the attached image.  Supports will be needed under this hook!
