This is a can holder for 50ml cans with the diameter of 66mm and a height of 168mm.
Glue the parts together, a tip is to glue the pins together at the same time as glueing the parts they are connecting.
Assembled the lenght is about 450 mm long, just a heads up that you might want to measure your fridge before printing.
A final “warning” not only is this longer than some frides (mine included it also takes a loot of fillament) - perhaps check out this can dispenser by @Chris_19788 instead?
The author remixed this model.
I made the model slightly wider to fit 50 cl cans.
