Valentine's is round the corner and I'm single, again, but I won't that let me down.

Here, have these tiny (~15*15mm) magnetic hearts. They take little time to print, so you can print an army of them to spread love far and wide.

Magnets are 4mm in diameter and 3mm tall, can be bought for cheap on sites like Aliexpress.

The magnets are press fit, no need for glue. I provided several hole diameters from 4mm to 4.4mm because your printer and parameter settings might affect the final diameter. For example, a smaller layer height results in more accurate diameters. I used 4.20mm.

For best adhesion and no failures when printing many at a time, properly clean your bed and set the temperature to 70ºC if you have a glass bed.
