Easy Community Floating Pellets Manual Feeder Top

Note: This is still a work in progress with a few bugs I want to work out, but it is functional.

This is a screw on cap for the aquarium co-op Easy Community Floating Pellets. You assemble the top, screw it onto the fish food container, then you can feed from it by holding the container upside down vertically and pushing the button. A consistent amount of fish food is dispensed each time.

The only extra pieces you will need are some springs. The springs I'm using are about 30 mm long. 

Assembly:

You will need one slider piece, one main_body piece, and one cover piece. You will also need two springs.

Place the slider in the opening of the main body. You will see a lip on one end of the slider. This lip should be facing down when assembling, so when assembly is done it should be facing up. You will have to force the slider into the body a bit since tolerance is tight.

On the slider and the main body, there are two holes depressed into each item. This is where the springs should go. Put the springs into the two holes like below.

Now, take the final cap piece, align the hole with the hole on the slider, and then push it in. This piece was made with NO tolerance, so you really have to force it in. After that, the item is fully assembled.
