Manual Fish Food Feeder

This is a lid you can create that allows you to dispense a consistent amount of fish food with only one hand.

Parts needed:

Non Printable Parts:
- Plastic Container: I use these from Amazon. I use the 8oz version.
- Springs: I bought this kit from Amazon, but really any springs will do (the design is pretty forgiving)

Printed Parts:
- Threaded Insert
- Main Housing
- Pusher

Assembly

1. Gather all of your parts.


2. Insert the pusher  into the main housing. The pusher has a lip, this should be facing down during assembly. There are two holes in the pusher and two holes in the housing. Place your springs in each of these holes, essentially connecting the two items.



3. Next, line up the holes between the threaded insert and the main body and push down. Each of the holes should snap into place, and the holes should now feel flush with the threaded insert. You could use a small amount of glue to make sure this is really in place, but I found once this is screwed in it shouldn't move at all.


4. All done! Just screw it onto the container tightly and it's now functional.


Usage: 

Hold the container upside down vertically. Push the button to load food into the pusher, and then release for the food to be dispensed from the top.

With using the Easy Community Floating Pellets from Aquarium Co-Op, I found that I dispense around 0.055g to 0.07g. Mostly hovering around the 0.6g area. It's fairly consistent! Here's an image of the average dispensed amount.
