I have been looking into having the foam insert of the hard shell backpack being cnc milled to fit the iPad or device of choice so that it fits snug and has no chance of being damaged in transit. I have emailed a few companies in the hope that this could be done at a small cost. here is enough space for it to be milled and it would mean a better fit rather than the device sliding around and possibly getting damaged. At the moment I simply remove the foam place the iPad in and close it up. I am planning to have it milled and having a velcro strap or tensioning strap placed to hold it in place. Does anyone here CNC Mill? Is it possible?
