About this 3D model
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!
