I saw Ollie's Vending Machine, but I wanted a larger version big enough for my Syrian hamster, Momma. Instead of making it bigger, I decided to make my own vending machine from scratch on DesignSpark since I needed some more practice.
Includes removable top and a hook at the back to help secure the vending machine to any part you want, or you can print the one without a hook.
You can slide in a picture of your choice, I picked an image off Google of sunflower seeds.
Original size comparison to Ollie's vending machine in picture 3.
I recommend this only be used during playtime as the top can fall off if your hamster is moving it a lot (picture 5 as an example).
Improvements to be made, but it is print ready. You can add supports, or print without at your own risk. I printed with supports and had some sanding to do. Make sure to flip the lid of the vending machine so it is upside down. No supports will be needed that way. I recommend you make sure the inside is free of leftover plastic before adding food.
