Sometimes, when disassembling some machine it is hard to find a good place where to put those little screws or metallic small pieces, and they always tend to get lost. So I designed a small tray with a 12x6mm cylindrical NIB (Neodymium Iron Boron) magnet embedded to ged rid of them. Print with support and press in the magnet.

Remember that only ferromagnetic material will get sticked on it, otherwise at least you will have a concave tray that the screws will tend to go to a position where you pick them easily. Or simply use it to put metallic objects in a cool position.

Easy, simple and cool, love things like this. Of course you can also use this as a fridge magnet or in your kitchen to prevent that egg's race to the soil, or even to keep that spoon still while you put a bit of salt or something on it.

It could be edited to allow a different magnet if you supply me the magnet dimensions. Just ask, I'll do it if I have the time!!

I ended designing a big brother for this thing here: http://www.thingiverse.com/thing:2027279

Enjoy!!
