Check out all my Gridfinity designs here

I wanted a shallow tray to hold my device charging base inside a drawer, so I made this to fit next to other Gridfinity things.

The charger I have is labelled “j5 Create” (I think it's a while-labelled charger). The tray is 100mm square.

There are two print profiles:

1. A standard version with 2 wall loops. This is a quicker print, but if you care, in a bright environment light shines through the walls, and you can see the infill pattern easily. Doesn't matter in a drawer or dark office etc.
2. Thicker walls (5 loops) so that light doesn't shine through, but longer print time.

If you're looking for another 3x3 tray with a slightly narrower rim/border, check out my matching set here (as this is a one-off).

Magnet holes a better press-fit.
