Aqua One FilterAir30 half lift pipe

thingiverse

I use this compact sponge filter for a temporary quarantine tank when I have a sick fish, but I discovered that the lift pipe that comes with the filter is a bit too tall for my tank (10cm high) so I decided to print a shorter replacement tube. It's exactly that - a tube. But if you own an Aqua One Filter Air 30 and want a shorter pipe, you'll have fun making one. For reference, the tube measures 19.7cm in outer diameter, 5 cm tall, with a wall thickness of 1.8mm.
