This is a Fluval (30) overflow aquarium tank filter. Designed in part by a buddy of mine for his tank. He said it works really good and thinks people will like it. Inspired me to put it on here.

Size: 140mm Height 73.4mm Width 57.4mm Depth

Flow tube: ID = 19.82 OD = 23.82 56mm overall length with a 45-degree angle cut out at the bottom to prevent the need for any supports during the print.

8mm stand of posts on the back - also with a 45-degree angle to prevent supports.
