Pancake Fridge Magnet

Hello, I would like to introduce you to my "pancake fridge magnet". In the profile, there are added negative parts in the shape of magnets that I used (8x2 mm), thanks to which there will be a hole for inserting the magnet.In the object tab, you can change the size of the negative part according to your magnet. Alternatively, delete my object and add, for example, a cuboid or a cube. The version that has holes from the bottom, in which case I recommend giving the exact size of the magnet and pounding it with a hammer, or 0.1 mm larger and sticking it with glue.
