Magnetic Bit Holder

A Magnetic Bit Holder! (like as if we haven't seen that before) I got this idea from a fancy expensive aluminum one that I've had for years, but it only came in one size, and I wanted a few more options. So I came up with this, I haven't seen one quite like this on here so I figured I would share it. It uses 3x10mm magnets, with a length of either 20mm or 40mm. Either size will work for all varieties. The size options range from 40mm with 8 bit slots, up to 160mm with 32 bit slots! Strong enough to hold most ¼" bits even upside down, I've been using it for a few weeks on my tool cart stuck to the underside of a lid, with no lost bits. As far as magnet orientation, I did some testing and found that an alternating pattern like a checkerboard seems to give the best holding strength, and also the easiest to set up. (See poorly made picture below) The magnets just slide in the slots from the end, alternate each one you slide into the slot, then add a drop of superglue or
