Parametric Kitchen Sink Strainer

The design is parametric and can be adjusted to fit drains of different sizes.  The FreeCAD model is provided, and one can easily adjust the diameter and depth of the strainer.

The model was built with PETG and does not require any support structure.  The magic is in the PrusaSlicer.  The infill was set to 50% to set the size of the holes in the strainer.  The infill pattern used was honeycomb.  The solid layers setting for top and bottom were both set to 0 and the vertical shells perimeters was set to 10.  This allowed the sidewalls to be solid and the infill/mesh to be exposed.
