I made these to catch items / food scraps going down the drain in the sink. It fits inside the drain with a mesh at the bottom and holes along the cylinder to allow water to still pass. I made 3 sizes (dimensions below) for what I needed. I have included the Solidworks files if you want to edit them yourself. The mesh should be at the top when printing.

Drain V2:
Inner Diameter = 40mm
Outer Diameter (Top) =71mm
Depth = 30mm

Drain V2 Small:
Inner Diameter = 25mm
Outer Diameter (Top )= 50mm
Depth = 9mm

Drain V2 Large:
Inner Diameter = 81mm
Outer Diameter (Top )= 113mm
Depth = 18mm
