Hex Bit Storage Rack with Magnetic Base

Added four embedded 8x2mm magnets into the base and chamfered top of the hex-shaped bit openings slightly.

Changed from my previous version and now using four 8x3mm magnets, one placed at the bottom (layer 1) and under each hex pocket so that the magnets will hold the bits in the rack and also secure the rack on a metal surface. At layer 13 you will be prompted to insert the four 8x3mm magnets if you use my .3mf file.

In my previous version with only two magnets there was not enough force to hold the rack on a vertical surface and the bits might come loose. I believe this version with four magnets will overcome all those problems. I also reduced the overall height by 3mm from the original version.

Print time is just under 2 hours with the settings I used.
