Parametric Floor Sewer Drain Cover

This drain cover was printed with PETG and the parametric design is in FreeCAD.  To adjust the diameter or thickness off the cover, simply modify the spreadsheet in the model. There are supports on the bottom with parameters that can be adjusted.

The primary reason for creating this model was to replace a metal plate that was rusting.  For strength reasons, this model was made with 100% infill.  Although the cover is sturdy, there is no guarantee as to how much weight this model will support.
