The tray and feeder is made so it is possible to stack them side by side or top/under on the IKEA SKADIS board. Hooks are included and step files for the slot and feeder.

The part named MIDDLE is if you want it stacked side by side at the same height since the slot on the IKEA board is offset I had to make two versions. 

Slot part is to make usage of the space between the feeding trays. Perhaps a part with holes for allen keys, screw driver or hooks that go under the tray. Be creative and show us what you are able to do with the space both under or between :-). 

PS!!.. Added one extra wide for lot of candy
