Desk Grommet Ring/Spacer

This model is for a ring for a standard 3" desk power grommet.  A desk grommet was installed in an RV and there was interference due to the depth of the device.  This ring was used to space the grommet off of the surface and provide adequate clearance behind the device.

This model was printed with PETG and no supports are required.  The thickness of the ring is 3/16 in and can be scaled in either the FreeCAD model or Prusa Slicer.
