Magnetically fridge mounted bottle holder for medium (65 - 75mm diameter) bottles. My bottle is 73mm diameter, fits perfectly with a little bit of gap so that it is easy to insert and remove.
Handy for keeping bottles in an easy to reach spot where they can dry so they don't get gross inside.
Print file pauses at the right layer so that you can insert up to 40 magnets inside the print.
Fits forty 6mm diameter by 2mm thick magnets. Might be overkill, but I like how securely it is attached to the fridge.
I attached a strip of electrical tape to the back of the print to increase the friction between the fridge and the bottle holder.
