Fridge Magnets / Whiteboard Magnets
These are easy print refrigerator / whiteboard magnets. I will try to include two profiles in each design – a full face and side profile – take your pick.
Each model has one or more recesses designed for a 10mm x 2mm rare earth magnet. Such magnets are small but powerful. I buy those 120 at a time here: https://www.amazon.com/gp/product/B07KMXSLRB
Just print and use a drop of hot glue or your favorite adhesive to attach a magnet into the recess. Unless I note on a specific design, these will print without supports and I usually go with 10% infill.
If you have some larger magnets on hand, obviously you can just glue those over the recess area or scale the model up.
