Designed to hold small parts (such as phone screws) for the duration of a short project (such as a screen replacement or other repair). Not much more than that, but very useful for my purposes.

Originally designed by Eirenliel. The 6 slot tray had holes in the trays when sliced with thick layer lines. Fixed with this file. The rest, which include 1 and 2 slot versions, can be found at the link below. https://thangs.com/designer/Eirenliel/3d-model/Gridfinity%20trays%20for%20small%20parts%20and%20ongoing%20projects-63131
