A simple magnetic drip trey I designed for my new kegerator build. In theory, could be used for any applications on a magnetic surface, I'm sticking it to the side of a fridge. 

Designed to work with two, 10mmx2mm magnets. They are a press-fit, however, a dab of superglue will ensure they don't come loose. Place them in the two holes at the rear, like in this picture:

I've included the step files for anyone that might want to resize the design for their application.
