desk/fridge/metal thing addon rack - magnet edition

I have a glass desk with a metal frame. I like a clean desk with no stuff in my way when i am tinkering or working. A few weeks ago i salvaged some nice magnets out of old HDDs. I put one and one together and designed this thing.

Glue a magnet in the rack and then put it on every metal surface you like.

I think this should also work for fridges and white boards.
With the magnets from a old HDD it is very solid. I think i could also make a bottle holder or something... lets see.
