File holder tray, Gridfinity 6U 11x4

a 3 part tray set for holding files, so you can print it on average 3d printers. The center section is 5x4 squares and the sides are 6U high. There are narrow-ish slots for medium sized files with no handles. The 8 wider slots are for bigger files, round files or triangular files, with handles, but the handles have to be on opposite ends (every other one). The middle section is full length (5x42 = 210mm) so you can glue it to the end trays if you want, or just so there is no gap. I made a 6U and 5U wall height end tray to fit my Kennedy tool box drawer front face lip. The 5 U fits under the front lip, the 6U fits the middle of the drawers..
