Made this tray for tool holder storage, figured I would share the files here in case one of you would find it useful. Measures 23"x6"x1.75", holds 10 standard Iso30 tool holders.
Feel free to make/edit/share.
3dm, f3d, dwg, and stl are at the link below. 10-count and 1-count versions are included in 3dm file.
