Refrigerator Number Magnets
I made the Refrigerator Alphabet Magnets that jgennari posted and I liked them so much that I followed that design to create matching numbers.
The files were created in Fusion 360 using the DIN Bold font that was referenced in the comments on the original make.
I used 5 x 2 mm neodymium magnets set in epoxy to complete the Numbers.
