After having to print a new base plate for my doorbell because the original broke. I decided to try my hand at creating a magnetic base as I was attaching it to my metal screen door. In the photos you will find my print, the magnet should be about the size of a US quarter, and the original base plate.
Print requirements:
Supports Everywhere needed
Print file the short size with the smallest opening as seen in the 2nd to last photo.
ABS or filament rated for outdoor use is recommended.
