Aquarium Fish Trap

This model attaches to a Kirks soft drink bottle (Aussie brand) which is about 89mm in diameter. The bottle can be dry fit.

The trigger is a paperclip bent so that a string can be attached to it, through the hoop and up, out of the tank.

The parts have been separated so that they can be printed in optimal orientation.

Print @ 100% infill so it does not float.

Glue the flange to the doorframe.
