bigger tray

SummaryI liked the parts tray this is based on, but I needed it to be a little different. So I recreated the box and drawers in tinkercad with a stronger shell and deeper drawers.large version uses 3 big drawers, small (same size as the 5 drawer versions) uses 1 small and 2 bigger drawers.I'm only using 1 and 2 chamber drawers as 4 would be awkward to pull screws out of, but if you need those the original project drawers should work if you change the height to 31x78mm, or 14x78mm for the small version(they almost fit in my case unaltered).Flip case over onto the bottom, not sure why but cura imports it upside down.5/15/20 - Added a 6 drawer version.3/20/21 - Replaced overwritten 6 drawer version.
