Sink Plug for 1.25" - 1.75"

Needed a sink plug for the laundry sink to bathe my pug. Home Depot didn't carry the right size. Designed to fit 1.25" to 1.75" drain hole with a strong ring for a beaded chain.
Edit 1: Replaced STL with a 50% scale version because Repetier Host seems to import it too large despite exact dimensions in FreeCad. FreeCAD file is attached if you want to make alterations.
