Fish Bowl Lid

thingiverse

This is a lid that I use on my fish bowl. I made it to keep filthy little cat paws from terrorizing the fish. I guess you could use it for anything, though. It has four holes for easy lifting. The STL is sized so that the inside of the lid is 127mm. If you need it to be a different size, scale by desired_size/127, times 100 if your software takes a percent. I printed on a Replicator 2 at Medium quality, With Support. A sharp wood chisel is a great way to remove the support. I designed the initial shape in Fusion 360, but then did postprocessing in Meshmixer to make it smoother. I have included the pre-smoothing .mix file.
