15" diameter acrylic dome on 17" flange - $50
 

This is for all you DIYers. I bought this acrylic dome to make a big DIY skimmer a year ago. I never got around to it and I have resorted to a retail bought skimmer.
The dome is 15" diameter, and the flange is 1" for total of 17"x17" square. Its made out of 1/4" cast acrylic.

Here's a picture of it. I still have the protective taping on the dome and edges.
