X-Acto #1 case with blade slots

Started with the scad file but then switched to Tinkercad as I find it easier and more intuitive.
Added slots for extra blades and hole to reach in to get the knife out easier. I also put pieces of magnetic tape in the blade slots they stay put. The tape I had wont really hold on to two blades. Maybe next time I'll add a hole for some rare earth magnets instead. The only other thing I might change is to shrink the top a bit to make it stay on better.
