2x5x6u Gridfinity tray for cordless rotary tool

This is based on Zack's Freedman's gridfinity project and it is a 5x2 tray, 6 units tall, with a cutout shaped to hold a FERM rotary tool or any similar dremel-like tool. In the unused space I added pits to hold chuck tips or other utensils at hand while working, the charging cable and the small wrench which comes with these tools.

This tray complements very well the nice box from @PjotrStrog which is the one pictured in my photo.
