About this 3D model

I made this after trying to use a similar device from http://www.thingiverse.com/thing:84405 Alas his only fit his drain, not mine. So a designed a new one in Solidiworks. There is a modest defect in that I need to add screwdriver clearance to mount the thing but I sorted that by snipping out one of the verticals. Of course you could remix it but as I needed only one I did not bother. Enjoy.
