Basic poop basket with 3x10 magnets. I needed something floating and not supported by any table below. I only used 4 magnets even is the model allows you to use more. The holes for the megnets are tight, no glue required. you might need to use a piler to enlarge then carefully to allow the magnet to fit. this is expected to avoid that the magnet, once in, can drop.

I have been using this for two months now and work just fine.
