There are various can dispensers available, but they all take up too much room in the refrigerator and in my opinion most don't look very nice. I was looking for a minimal way to organize cans in my refrigerator and this is what I came up with.

The uploaded files are broken into 2 and 3-can slot versions because that's what fits on my printer and in my refrigerator. I have uploaded the Fusion360 file which is fully parametric so that you can easily adjust it to your own printer and refrigerator. You need a total of 5 slots in order to be able to hold a full 12-pack of cans, but a 3-slot stacker will hold 6 cans just fine on its own if you have the vertical space. When placed end-to-end, the slots are spaced correctly, so they can be glued together to form longer pieces.

Parameter details (the favorited parameters are the ones you are most likely to want to adjust):

• can_count - number of can slots. It takes 5 cans to fit a full 12 pack, but only 3 slots fit on my printer
• can_height - the width is calculated as 66% of the can height
• can_diameter - the slots are spaced such that cans fit together with minimal gaps
• length_adjustment - adjust slightly positive or negative to either extend or slightly chop one end to fit on a shelf or print bed

Files are uploaded in the recommended print orientation: on their side. This is because 3D printers are much better at producing curves in the x-y plane than any plane on the z-axis. Files also have a 1mm chamfer on the top and bottom because they look nice, but also prevent any weirdness from elephant's foot.

You can print this in any material. I printed mine out of Inland Matte Black PLA using a layer height of 0.2mm. The part doesn't need much strength so you can use any infill, but I used 15% adaptive cubic.
