I created a customizable magnetic knife bar. Of cousre it's not limited to knives :-) As you can see in one of my pictures, I used it for some tools.
All important values are custamizable, like length, width, magnet diameter, magnet height, magnet placement offset and the corner radius. The number of magnets will be calculated, depending on the length, the magnet diameter and the placement offset.
I used some N52 neodym magnets with a diameter of 10mm and a height of 5mm. The uploaded STL is customized for these magnets. I used these relative cheap magnets http://www.banggood.com/10pcs-10mm-x-5mm-N52-Strong-Rare-Earth-NdFeB-Neodymium-Disc-Magnets-p-988441.html
Changes:
1) I added an option to create screw holes, if you don't trust the adhesive tape to hold the weight. There is a small layer of 0.1mm in the screw holes, to optimize them for printing.
