Raspberry Pi 3 Magnetic Case Bottom (for Core One)

bullitt168 previously remixed Malolo's great series of cases to add magnets for mounting to the Core One. His design didn't quite meet my needs as the magnet pockets were too deep and the protrusion into the bottom of the case caused fit issues with the cover, and left the magnets exposed. This case adds eight, 10x3 magnets for greater pull, which are completely embedded in the model. To print, slice and add a pause at the last layer before the magnets are covered over. Insert the magnets when the printer pauses. You can use this base with any cover from Malolo's original design. I used PETG, but PLA would likely work fine. 15% grid infill.
