Automatic fish feeder with large capacity and easy to use. Ready for 3D printing. The model use a 0.4 mm tollerance for moving parts so make sure that is a good resolution for your printer, you can easily change the tollerance in the parameters window if you use fusion3D file (contact me if you need any help). Is designed for middle size fish tank and the dispenser is controlled by a servo motor. It has 12.00 mm fish tank joint, you can also change this value in the fusion parameters. I used Ardiuno as controller for my project and you can find the code in the Fish_Feeder Arduino.rar files.
