Been meaning to post this for a long time, but this was one of the first big designs I made. Takes about 10 hours to print each tray, but they are pretty big (134mm long, 108mm wide, 64mm tall outside dimensions) and stack on top one another. The odd dimensions came from wanting to have it perfectly in my desk drawer at work, which it did! A success in my book.

I have also included my Simplify3D support file, as you will want supports around the bottom perimeter and for the holes if you want them clean or don't want to worry about bridging.
